Description

本発明は、磁気ディスク装置に係り、特に、レーザー光をヘッドと一体で形成されている磁気ヘッド内の近接場光学素子に導く導波路を備えたヘッド支持機構及び磁気ディスク装置に関するものである。   The present invention relates to a magnetic disk apparatus, and more particularly to a head support mechanism and a magnetic disk apparatus having a waveguide for guiding laser light to a near-field optical element in a magnetic head formed integrally with the head.

近年、磁気ディスク装置の記録密度を飛躍的に向上させる技術の一つとして、熱アシスト記録が挙げられる。熱アシスト記録とは、ディスク上の数十ｎｍ×数十ｎｍ程度の微小領域に２００℃以上の熱と磁場を加えることで、ディスク上にデータを記録するものである。この微小領域を加熱する機構として、記録磁極近傍に配置した近接場光学素子でレーザー光を近接場光に変換して利用することが考えられている。   In recent years, as one of the techniques for dramatically improving the recording density of a magnetic disk device, there is a heat-assisted recording. In the heat-assisted recording, data is recorded on the disk by applying heat and a magnetic field of 200 ° C. or more to a minute area of about several tens of nm × several tens of nm on the disk. As a mechanism for heating this minute region, it is considered that a near-field optical element arranged near the recording magnetic pole is used by converting laser light into near-field light.

また、通常、磁気ディスク装置のサスペンションは、フレクシャとロードビームから成る。フレクシャはヘッドと直接接合される薄い板状の部材であり、ヘッドの姿勢を拘束しない形になっている。ロードビームは、フレクシャを介してディスク面に押し付ける方向にヘッドに荷重を加えるための板状の部材である。フレクシャとロードビームは溶接により接合されている。   In general, the suspension of the magnetic disk device is composed of a flexure and a load beam. The flexure is a thin plate-like member that is directly joined to the head and has a shape that does not restrict the posture of the head. The load beam is a plate-like member for applying a load to the head in a direction to be pressed against the disk surface via the flexure. The flexure and the load beam are joined by welding.

従来、この種のヘッド支持機構としては、例えば、特開２００３−６９１２号公報（特許文献１）がある。特許文献１によるヘッド支持機構においては、フレクシャに相当する部分が導波路で形成されており、この導波路は光が通る高屈折率のコアを低屈折率のクラッドで覆い形成されている。コアの端面を導波路の途中、かつ、ヘッドとの固定面に設けることで、光をクラッドの中で一旦拡大させ、その後、反射面でヘッド側に反射させる。反射した光束をマイクロレンズで集光した上で、近接場光学素子に照射させることで、ヘッドの姿勢によらず高強度の光を近接場光学素子に光を導くことを可能としている。   Conventionally, as this type of head support mechanism, for example, there is JP-A-2003-6912 (Patent Document 1). In the head support mechanism according to Patent Document 1, a portion corresponding to a flexure is formed by a waveguide, and the waveguide is formed by covering a high refractive index core through which light passes with a low refractive index cladding. By providing the end face of the core in the middle of the waveguide and on the fixed surface with the head, the light is once expanded in the clad and then reflected to the head side by the reflecting surface. The reflected light beam is condensed by a microlens and irradiated to the near-field optical element, so that high-intensity light can be guided to the near-field optical element regardless of the posture of the head.

また、他のヘッド支持機構に係わるものとして、例えば、特開２００１−１０１７０４号公報（特許文献２）がある。特許文献２によるヘッド支持機構においては、フレクシャのヘッド接続面の裏面に導波路が配置されている。   Another example of the head support mechanism is disclosed in Japanese Patent Application Laid-Open No. 2001-101704 (Patent Document 2). In the head support mechanism according to Patent Document 2, a waveguide is disposed on the back surface of the head connection surface of the flexure.

特開２００３−６９１２号公報JP 2003-6912 A 特開２００１−１０１７０４号公報JP 2001-101704 A

通常のサスペンションでは、フレクシャにエッチングでパターンを切り、スライダ接合部を柔軟に支持する構造になっている。これによりヘッドは、エアベリングサーフェス（ＡＢＳ）で発生する正圧力及び負圧力とディンプルを介してロードビームから伝わる押付荷重が釣合う浮上量及び姿勢でディスク上を安定浮上し、ディスクの面振れやうねりにも追随している。また、これにより外部から衝撃を受けた場合やディスク及びディスク上の異物に接触した場合でも、クラッシュすることなく浮上することができる。   A normal suspension has a structure that flexibly supports a slider joint by cutting a pattern in a flexure by etching. As a result, the head stably floats on the disk with the flying height and posture in which the positive and negative pressures generated on the air beveling surface (ABS) and the pressing load transmitted from the load beam through the dimples are balanced. It follows the swell. In addition, even when a shock is applied from the outside or when a disk and a foreign object on the disk are contacted, it is possible to float without crashing.

しかしながら、特許文献１に開示されるヘッド支持機構では、導波路がスライダ接合部全体を覆う構造となっている。そのため、導波路の表面に接着剤を塗布あるいはヘッドの接合面に接着剤を塗布することによりヘッドと導波路を接合する場合、接着剤の厚さのばらつきにより、スライダ接合面に対してヘッドが傾いて取り付き、ヘッドの浮上量や姿勢に大きく影響を及ぼすようになり、ヘッドの安定浮上に悪影響を及ぼす恐れがある。   However, the head support mechanism disclosed in Patent Document 1 has a structure in which the waveguide covers the entire slider joint. For this reason, when the head and the waveguide are joined by applying an adhesive to the surface of the waveguide or by applying an adhesive to the joint surface of the head, the head may move against the slider joint surface due to variations in the thickness of the adhesive. It tilts and attaches, and it greatly affects the flying height and posture of the head, which may adversely affect the stable flying of the head.

また、特許文献２に開示されるヘッド支持機構では、導波路がフレクシャのスライダ接合面の裏側に配置されており、導波路端の光の出口からヘッドまでの距離が長く、光の結合損失が大きくなる恐れがある。   In the head support mechanism disclosed in Patent Document 2, the waveguide is disposed on the back side of the slider joint surface of the flexure, the distance from the light exit at the end of the waveguide to the head is long, and the coupling loss of light is low. There is a risk of growing.

本発明の目的は、導波路とヘッドとの光の結合損失を小さくし、且つヘッドの安定浮上を実現し得るヘッド支持機構及びそれを備えた磁気ディスク装置を提供することにある。   An object of the present invention is to provide a head support mechanism that can reduce the coupling loss of light between a waveguide and a head and realize stable flying of the head, and a magnetic disk device including the head support mechanism.

本発明は、導波路を、スライダを弾性支持する弾性支持部材のスライダ接合面の中央部であって、スライダ接合面の長手方向に沿って配置すると共に、スライダ接合面の前記磁気ヘッドとは反対側の一方端から延伸し、回路材のスライダ接合面の磁気ヘッドとは反対側端の一方端側から延伸した部分が弾性支持部材または回路材に接続され、スライダ接合面に回路部材の一部とほぼ同じ厚さを有する補助部材を設けたを設けたことを特徴とする。   In the present invention, the waveguide is disposed at the center of the slider joint surface of the elastic support member for elastically supporting the slider, and is disposed along the longitudinal direction of the slider joint surface, and is opposite to the magnetic head on the slider joint surface. A portion extending from one end of the circuit material and extending from one end side of the slider joint surface of the circuit material opposite to the magnetic head is connected to the elastic support member or the circuit material, and a part of the circuit member is connected to the slider joint surface. And an auxiliary member having substantially the same thickness as that provided.

尚、補助部材は、スライダ接合面の長手方向両側端部に導波路と平行に配置され、導波路とほぼ同じ厚さを有することを特徴とする。   The auxiliary member is arranged in parallel with the waveguide at both ends in the longitudinal direction of the slider joint surface, and has substantially the same thickness as the waveguide.

これにより、スライダを接着剤により弾性支持部材のスライダ接合面に接合する場合において、接着剤がスライダと導波路との間及びスライダと第１の補助部材の間に充填され、スライダ接合面に対し精度良くスライダを接合することが可能となる。   Accordingly, when the slider is bonded to the slider joint surface of the elastic support member by the adhesive, the adhesive is filled between the slider and the waveguide and between the slider and the first auxiliary member, and the slider is bonded to the slider joint surface. It becomes possible to join the slider with high accuracy.

本発明によれば、端部に磁気ヘッドが形成されたスライダを、弾性支持部材のスライダ接合面に傾かずに取り付けることができ、浮上量や姿勢に与える影響を小さくすることができる。   According to the present invention, the slider having the magnetic head formed at the end can be attached to the slider joint surface of the elastic support member without being inclined, and the influence on the flying height and the posture can be reduced.

本発明の実施の形態を以下図面を用いて説明する。
図１は、本発明によるヘッド支持機構を搭載した磁気ディスク装置の斜視図である。 Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of a magnetic disk drive equipped with a head support mechanism according to the present invention.

図１において、磁気記録媒体であるディスク１は回転可能に支持されている。近接場光発生素子を備えた磁気ヘッド２はスライダ３の端面に一体で形成されており、スライダ３は、ディスク１の記録面上を所定の間隔で浮上している。スライダ３は、導波路４（図２以降で説明）を備えたサスペンション５に支持されている。サスペンション５は、ロードビーム７と弾性支持部材としてのフレクシャ６から成り、スライダ３は、その姿勢が拘束されない状態でフレクシャ６に柔軟に支持されている。ロードビーム７は、フレクシャ６を介して、ディスク１に押し付ける方向にスライダ３に荷重を加えている。サスペンション５はキャリッジアーム８に支持されており、キャリッジアーム８はピボット９を回転軸として揺動可能に支持されている。   In FIG. 1, a disk 1 that is a magnetic recording medium is rotatably supported. The magnetic head 2 provided with the near-field light generating element is integrally formed on the end surface of the slider 3, and the slider 3 floats on the recording surface of the disk 1 at a predetermined interval. The slider 3 is supported by a suspension 5 including a waveguide 4 (described in FIG. 2 and subsequent figures). The suspension 5 includes a load beam 7 and a flexure 6 as an elastic support member, and the slider 3 is flexibly supported by the flexure 6 in a state in which the posture is not restricted. The load beam 7 applies a load to the slider 3 through the flexure 6 in a direction in which the load beam 7 is pressed against the disk 1. The suspension 5 is supported by a carriage arm 8, and the carriage arm 8 is supported so as to be swingable about a pivot 9 as a rotation axis.

ボイスコイルモータ１０を駆動させることにより、ピボット９を回転軸として、キャリッジアーム８を揺動させ、回転するディスク１に対して、近接場光発生素子を備えた磁気ヘッド２をディスク１上の所望のトラック上に移動させ、情報の記録，再生を行う。   By driving the voice coil motor 10, the carriage arm 8 is swung about the pivot 9 as a rotation axis, and the magnetic head 2 having a near-field light generating element is desired on the disk 1 with respect to the rotating disk 1. To record and play back information.

以下では、図面を用いてヘッド支持時機構を中心に説明する。   Below, it demonstrates centering on the mechanism at the time of a head support using drawing.

FIG. 3 is an enlarged view of the tip of the head support mechanism before mounting the slider according to one embodiment of the present invention. 4 is a cross-sectional view taken along the line AA 'in FIG.

ロードビーム７と共にサスペンション５を構成するフレクシャ６は、例えば薄肉のステンレス製板材を用いてその一部に切り欠きを設けることで形成される。そして図３に示めされるように、フレクシャ６は、ステンレス基板６１と、ステンレス基板６１と両持ち梁にて連続するスライダ接合面６２からなっている。フレクシャ６上には、回路材６３，導波路４，導波路４と同じ厚さの補助部材１２ａ，１２ｂが形成されている。ここで回路材６３とは、例えばポリイミド，銅配線，ポリイミドの順に積層形成された配線部材である。フレクシャ６のスライダ接合面６２の中央には導波路４が配置され、更に導波路４に平行にスライダ接合面６２の長手方向両側端部近傍には導波路４と同じ厚さの補助部材１２ａが、また、導波路４とほぼ直交するようにスライダ接合面６２の一方端部近傍には導波路４と同じ厚さの補助部材１２ｂが配置されている。スライダ３は接着剤（図示なし）によって、フレクシャ６のスライダ接合面６２に接続されるが、接着剤（図示なし）は、フレクシャ６のスライダ接合面６２の中央に配置された導波路４と導波路４と同じ厚さの補助部材１２ａ，１２ｂの間の空間に盛られる。具体的には、当初、接着剤（図示なし）は導波路４より高く盛られるが、スライダ３を押し付けることにより、スライダ３と導波路４，スライダ３と補助部材１２ａ，１２ｂの間に流れ込み、その結果、スライダ３とスライダ接合面６２は隙間無く接続され、スライダ３は、スライダ接合面６２に傾くことなく精度よく接続できる。   The flexure 6 that constitutes the suspension 5 together with the load beam 7 is formed, for example, by using a thin stainless steel plate and providing a notch in a part thereof. As shown in FIG. 3, the flexure 6 includes a stainless steel substrate 61 and a slider joint surface 62 that is continuous with the stainless steel substrate 61 by a cantilever beam. On the flexure 6, auxiliary members 12a and 12b having the same thickness as the circuit material 63, the waveguide 4 and the waveguide 4 are formed. Here, the circuit material 63 is a wiring member formed by laminating, for example, polyimide, copper wiring, and polyimide in this order. The waveguide 4 is disposed in the center of the slider joint surface 62 of the flexure 6, and auxiliary members 12 a having the same thickness as the waveguide 4 are provided in the vicinity of both ends in the longitudinal direction of the slider joint surface 62 in parallel to the waveguide 4. Further, an auxiliary member 12b having the same thickness as that of the waveguide 4 is disposed in the vicinity of one end portion of the slider joint surface 62 so as to be substantially orthogonal to the waveguide 4. The slider 3 is connected to the slider joint surface 62 of the flexure 6 by an adhesive (not shown). The adhesive (not shown) is guided to the waveguide 4 disposed at the center of the slider joint surface 62 of the flexure 6. It is built in the space between the auxiliary members 12a, 12b having the same thickness as the waveguide 4. Specifically, the adhesive (not shown) is initially placed higher than the waveguide 4, but by pressing the slider 3, it flows between the slider 3 and the waveguide 4, the slider 3, and the auxiliary members 12 a and 12 b, As a result, the slider 3 and the slider joint surface 62 are connected without a gap, and the slider 3 can be accurately connected without being inclined to the slider joint surface 62.

熱アシスト記録用磁気ヘッド２としては、例えば「Flying demonstration and analysis of pico slider with optical waveguide for heat assisted magnetic recording」(The 19th Magnetic Recording Conference (TMRC) 2008, Singapore, July 29-31, 2008）に開示されるように、スライダ３の磁気ヘッド２付近から光を導入する構造になっているものもある。このような構造のスライダ３を用いた場合において、本実施例によれば、上述のとおり導波路４がスライダ３の先端部に一体形成された磁気ヘッド２まで延伸する構造であり、かつ、導波路４とスライダ３が直接接続されるので、導波路４から磁気ヘッド２に光を導入入れるときのロスを小さくすることが可能となる。 As the heat-assisted recording magnetic head 2, for example, "Flying demonstration and analysis of pico slider with optical waveguide for heat assisted magnetic recording " (The 19 th Magnetic Recording Conference ( TMRC) 2008, Singapore, July 29-31, 2008) to As disclosed, there is a structure in which light is introduced from the vicinity of the magnetic head 2 of the slider 3. In the case where the slider 3 having such a structure is used, according to the present embodiment, the waveguide 4 extends to the magnetic head 2 integrally formed at the front end portion of the slider 3 as described above, and is guided. Since the waveguide 4 and the slider 3 are directly connected, it is possible to reduce a loss when light is introduced from the waveguide 4 into the magnetic head 2.

本実施例は、従来の磁気記録方式、すなわち、熱アシスト方式を用いない磁気ディスク装置用ヘッド支持機構であり、実施例１における導波路４を有していない。   This embodiment is a head support mechanism for a magnetic disk device that does not use a conventional magnetic recording method, that is, a heat assist method, and does not have the waveguide 4 in the first embodiment.

図５は本発明の一実施例である導波路４を有さないヘッド支持機構の先端拡大図、図６は図５のヘッド支持機構のスライダ搭載前の状態を示す図である。図中実施例１と同一のものには同一の符号を付している。   FIG. 5 is an enlarged view of the tip of a head support mechanism that does not have a waveguide 4 according to an embodiment of the present invention, and FIG. 6 is a diagram showing a state of the head support mechanism of FIG. In the figure, the same components as those in the first embodiment are denoted by the same reference numerals.

本実施例の基本構成は実施例１と同じであるが、実施例１の導波路４の代わりに回路材６３の一部を用い、実施例１の導波路４と同じ厚さの補助部材１２の代わりに回路材６３と同じ厚さの補助部材１３ａ及び１３ｂを用いている。図５において回路材６３のアーム６３１は、フレクシャ６のステンレス基板のアーム６１１と重なる部分を除いては、フレクシャ６のステンレス基板６１と重なっていない。そのため、フレクシャ６のスライダ接合面６２は、フレキシブルな動きが可能となっている。図６を用いて具体的に説明すると、フレクシャ６のスライダ接合面６２の中央には回路材６３の一部６３２が延伸され配置され、更に回路材６３の一部６３２に平行にスライダ接合面６２の長手方向両側端部近傍には、回路材６３の一部６３２４と同じ厚さの補助部材１３ａ，１３ｂが配置されている。   Although the basic configuration of the present embodiment is the same as that of the first embodiment, a part of the circuit material 63 is used instead of the waveguide 4 of the first embodiment, and the auxiliary member 12 having the same thickness as the waveguide 4 of the first embodiment is used. Instead, auxiliary members 13a and 13b having the same thickness as the circuit material 63 are used. In FIG. 5, the arm 631 of the circuit material 63 does not overlap with the stainless steel substrate 61 of the flexure 6 except for a portion that overlaps with the arm 611 of the stainless steel substrate of the flexure 6. Therefore, the slider joint surface 62 of the flexure 6 can move flexibly. Specifically, a part 632 of the circuit material 63 is extended and arranged at the center of the slider joint surface 62 of the flexure 6, and further, the slider joint surface 62 is parallel to the part 632 of the circuit material 63. The auxiliary members 13a and 13b having the same thickness as the part 6324 of the circuit material 63 are disposed in the vicinity of both end portions in the longitudinal direction.

図７は、実施例２の効果を示すヘッド支持機構の振動特性図であり、図５と同一構成のヘッド支持機構を回転円板間に配置したときの、スライダ３の短手方向（紙面縦方向）の振動、すなわちヘッドの流体起因振動の測定結果を示している。横軸は、ヘッド支持機構取り付け面から円板までの距離である。本実施例によるヘッド支持機構の振動特性１４に対し、回路材６３の一部６３２を有さない従来のヘッド支持機構の振動特性１５は大きい。これは回路材６３の一部６３２によりフレクシャ６のスライダ接合面６２とロードビーム７の相対振動が抑制されるためである。   7 is a vibration characteristic diagram of the head support mechanism showing the effect of the second embodiment. When the head support mechanism having the same configuration as that of FIG. Direction), that is, the measurement result of the fluid-induced vibration of the head. The horizontal axis is the distance from the head support mechanism mounting surface to the disc. In contrast to the vibration characteristic 14 of the head support mechanism according to this embodiment, the vibration characteristic 15 of the conventional head support mechanism that does not have the part 632 of the circuit material 63 is large. This is because the relative vibration between the slider joint surface 62 of the flexure 6 and the load beam 7 is suppressed by the part 632 of the circuit material 63.

尚、本実施例においても実施例１と同様に、スライダ３を、スライダ接合面６２に傾くことなく精度よく接続することが可能となる。   In the present embodiment, similarly to the first embodiment, the slider 3 can be accurately connected without being inclined to the slider joint surface 62.
