Abstract

PURPOSE:To improve the position accuracy of a magnetic head by increasing the rigidity of supporting parts arranged on diagonal positions through the centroid of a magnetic recorder in the thickness direction and providing elasticity to the other supporting parts in the thickness direction. CONSTITUTION:The rigidity of the supporting parts 6b, 6d arranged on the diagonal positions through the centroid 10 of the magnetic recorder in the lateral direction shown by an arrow 7 and the other supporting parts 6a, 6b are provided with elasticity. In the thickness direction of the recorder shown by an arrow 8, the rigidity of the supporting parts 6a, 6c on the diagonal positions through the centroid 10 is increased and the supporting parts 6b, 6d are provided with elasticity. If the planeness of the fitting face of a fixing base has a deviation, the magnetic recorder is fixed on a face connecting the fitting faces 11c, 11a because the fitting parts 4a, 4c are fixed through the supporting parts 6a, 6c having high rigidity in the arrow 8 direction, and when the position of the fitting face 1b is deviated, the positional shear is absorbed by the supporting parts 6b, 6d having elasticity and a frame 1 can be prevented from being deformed. Consequently, the accuracy of the position of the magnetic head can be improved.

である点だけである。Since it is almost the same as the fixing base 11 shown in FIG. 3, the explanation will be omitted, but the difference from the fixing base 11 shown in FIG. 3 is that the holes drilled in the mounting surfaces 12b and 12C are elongated holes. There are only dots.

(Mounting surfaces 12a and 12d
It is positioned by the hole drilled in the hemlocked surface 12b,
You can freely tighten the screw within the elongated hole drilled in 2c. ), so I would like to add that the characteristics will further improve.

また、本発明の他の特徴である耐振動性について少し説
明する。Further, vibration resistance, which is another feature of the present invention, will be briefly explained.

第１図に示す本発明の一実施例をもとに説明すると、本

磁気記録装置の厚み方向（矢印８方向）へと振動が加わ
った場合、該方向に対しては、前記支持部６ｃＬｓ６ｃ
の剛性が高いので、剛いバネとして作用し、その共振点
の周波数が高くなると共に、共振点での振面が小さい。To explain based on one embodiment of the present invention shown in FIG. 1, a magnetic recording device using the mounting structure of the present invention is mounted on a fixing base 1.
1 (shown in FIG. 3), and when vibration is applied to the fixing base 11 in the thickness direction (direction of arrow 8) of the magnetic recording device, the support portion 6cLs6c
Since it has high rigidity, it acts as a stiff spring, the frequency at its resonance point becomes high, and the vibration surface at the resonance point is small.

前述のような共振による力は磁気記録装置の重心１０に
作用すると考えても等価であり、共振による力が重心１
０を前記厚ろ方向（矢印８方向）に作用すると考えると
、該方向に対し剛性の高い支持部６ａ、ｆ３ｃが重心１
０をおよそ挾むことにより、磁気記録装置がローリング
せしめられる共振をも防ぐことが可能である。It is equivalent to consider that the force due to resonance as described above acts on the center of gravity 10 of the magnetic recording device;
0 acts in the thickness direction (arrow 8 direction), the support parts 6a and f3c having high rigidity in this direction have a center of gravity 1
By approximately sandwiching 0, it is also possible to prevent resonance that would cause the magnetic recording device to roll.

もう少し説明すると、前記構成において、厚み方向（矢

働く力による仮想軸まわりのモーメントが増大し、磁気
記録装置全体がその厚み方向に共振するのではな（、仮
想軸まわりの回動の共振を起こしてしまう。To explain a little more, in the above configuration, the frame 1 rolls at the time of resonance with a line connecting the attachment part 4a14c via the support part 6a16c having high rigidity in the thickness direction (arrow 8 direction) as an imaginary axis. In this situation, the center of gravity 1
The further away 0 is from the imaginary axis, the more the moment around the imaginary axis due to the force acting on the center of gravity 10 increases, causing the entire magnetic recording device to resonate in its thickness direction (the rotation around the imaginary axis increases). This causes dynamic resonance.

該現象は重心１０をはさまない２本の支持部の剛性を高
（した場合を仮想するとより明確になる。This phenomenon will become clearer if we imagine a case in which the rigidity of the two supporting parts that do not sandwich the center of gravity 10 is increased.

以上より、耐振動性を向上させるには、剛性が高い２本
の支持部が重心をおよそはさむ事が不可欠である。From the above, in order to improve vibration resistance, it is essential that the center of gravity be sandwiched between two highly rigid support parts.

さらに、各支持部６　ａ、６　ｂｓ　８　Ｃ％　８　ｄ

をつけ加えておく。Furthermore, each support part 6 a, 6 bs 8 C% 8 d
It should be added that by changing the rigidity of each support part, it is possible to change the resonance point of each support part, further improving vibration resistance.

Only the mounting portions 32a and 32c are connected through the as 36c, and the mounting portions 32b and 32d are provided on a convex portion projecting outward from the frame 31.

て大きい。As described above, according to the invention, the installation mounting part is connected to the frame via the support part, and the magnetic recording device
By increasing the rigidity of the two support parts located diagonally across the center of gravity of the H position, and by making the other support parts elastic in the above direction, the force generated when fixing the frame is reduced. It is possible to absorb this with the elastic support portion, prevent deformation of the frame, and prevent deterioration of positional accuracy of the magnetic head due to deformation of the frame. In addition, with respect to vibration transmitted through the installation mounting part, the high rigidity of the two diagonally located support parts raises the resonance point and reduces the amplitude, improving IJi resistance. , the reliability of the magnetic recording device can be improved, and the practical effects of the present invention are extremely large.

磁気記録装置の取付構造。A frame forms the structural framework of a magnetic recording device that rotates a magnetic recording medium and moves a magnetic head to perform recording and reproduction, and a plurality of frames are provided on the bottom or side surface of the frame in order to install the magnetic recording device. In the mounting structure for a magnetic recording device having a mounting part fixed by a screw fixing means, the mounting part is connected to the frame via a support having spring properties, and the mounting part is fixed at the bottom surface. Regarding the supporting parts to be connected, the rigidity of the two supporting parts located approximately diagonally across the center of gravity is made high in the thickness direction of the magnetic recording device, and the other supporting parts are made rigid in that direction. On the other hand, for the support part connected to the mounting part that is configured to have elasticity and fixed on the side, the rigidity of the two support parts located approximately diagonally across the center of gravity of the magnetic recording device 1. A mounting structure for a magnetic recording device, characterized in that the support portion is made higher in the lateral direction, and the other support portion is configured to have elasticity in that direction.
