本考案は回転型アクセス機構に関し、さらに詳しく述べ
るならばトラック接線方向とヘッドの向きのズレを小さ
くした回転型アクセス機構に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary access mechanism, and more specifically, to a rotary access mechanism that reduces the deviation between the track tangential direction and the head orientation.
従来、磁気ディスク装置においては、直線運動式リニア
モータによるヘッドアクセスが一般的であったが、回転
式アームによるアクセスが構造を小さくできる等の利点
を有するため近年使用の可能性が出て来た。In the past, in magnetic disk drives, head access using a linear motion type linear motor was common, but access using a rotary arm has recently become a possibility as it has advantages such as being able to make the structure smaller. .
一方、回転式のアームにおいては、第１図に示すように
アーム１の回転中心２とアーム１の先端に設けられたコ
ア３を結ぶ線とコア３の向きは平行のものが一般的であ
る。On the other hand, in a rotary arm, as shown in Fig. 1, the core 3 is generally oriented parallel to the line connecting the rotation center 2 of the arm 1 and the core 3 provided at the tip of the arm 1. .
このためどこか１トラツクしかコアの向きとトラック接
線１ｄ一致せず、コア３の向きはディスク５のトラック
４の位置により本質的にずれを生じる。For this reason, the direction of the core coincides with the track tangent 1d for only one track, and the direction of the core 3 essentially deviates depending on the position of the track 4 on the disk 5.
トラック接線とコア方向のずれの最大角度はθで示され
る。The maximum angle of deviation between the track tangent and the core direction is indicated by θ.
このずれの最大角度を小さくするためにはアームの長さ
ｔを大きくすれば良いが、この場合装置全体の大きくな
る、アーム自体の重量が重くなりアクセスの速さが遅く
なる等の問題がある。In order to reduce the maximum angle of this deviation, the length t of the arm can be increased, but in this case there are problems such as the overall size of the device, the weight of the arm itself becoming heavy, and the speed of access slowing down. .
したがって、本考案の目的は従来技術の欠点を除去し、
出来るだけ短いアームでトラック接線方向とコアの向き
のずれを小さくすることを可能にする回転型アクセス機
構を提供することである。Therefore, the purpose of the present invention is to eliminate the drawbacks of the prior art and
To provide a rotary access mechanism that makes it possible to reduce the deviation between the track tangential direction and the core direction with an arm as short as possible.

。The rotary access mechanism according to the present invention includes a rotating disk-shaped magnetic recording medium and a core for reading information from the recording medium at one end of an arm that can rotate around a point outside the recording medium. In the rotary access mechanism, the core is arranged at a certain angle with a line connecting the rotation center of the arm and the core so that the track tangential direction of at least the outermost track and the innermost track is substantially parallel to the core. The device is characterized in that the device is attached to the arm.
次に、本考案の回転型アクセス機構を図面により説明す
る。Next, the rotary access mechanism of the present invention will be explained with reference to the drawings.
第２図に示すようにアーム１のコア３を回転中心２とコ
ア３を結ぶ線と一定の角度を設けて取付ける。As shown in FIG. 2, the core 3 of the arm 1 is attached at a certain angle to a line connecting the rotation center 2 and the core 3.
すなわち本考案ではディスク５の最外同トラック４及び
最内周トラック４においてトラック接線方向とコア３と
が略平行になるようにコア３を取付けたものである。That is, in the present invention, the core 3 is installed in the outermost track 4 and the innermost track 4 of the disk 5 so that the track tangential direction and the core 3 are substantially parallel.
このように構成する事により本考案においてはトラック
接線とコア３の最大方向ずれθは著しく小さくなり、し
かもこれはアームの長さｔを長くする事なく達成出来る
。With this configuration, in the present invention, the maximum directional deviation θ between the track tangent and the core 3 is significantly reduced, and this can be achieved without increasing the arm length t.
以上のように本考案においては回転型アクセス機構にお
・いて、トラックの接線方向と、コアの角度ずれを小さ
くする事が可能となった。As described above, in the present invention, it is possible to reduce the angular deviation between the tangential direction of the track and the core in the rotary access mechanism.
