ズドルーグサーボ方式を利用する装置が増えてきた。In recent years, with the increase in the capacity and recording density of devices, the allowable off-track amount has become smaller. ,6. The ability required for vibration resistance during recording and reproduction is significant. On the other hand, the resonance point of the anti-vibration rubber is set to a low frequency to widen the frequency range that corresponds to the anti-vibration region. Furthermore, in order to improve head positioning accuracy (reduce off-track), an increasing number of devices are using the closed-Drug servo system, which feeds back and uses positioning signals from the head.

質をやわらかくする。Regarding the frequency characteristics of the positioning servo characteristics, the positioning characteristics are better in the low frequency range, so the resonance frequency of the anti-vibration rubber is designed to be low. A first method for lowering this resonant frequency is to soften the material of the rectangular rubber shown in FIG.

In addition, soft, high-damping rubbers have been developed, but they have the problems of high cost and a high rate of change in rubber hardness due to temperature changes.

ければならず、設計の自由度がへる。@1. In both methods, since the vibration isolating rubber has a small spring constant of φ, it is necessary to provide a large shock shaking space to accommodate the impact of moving and transporting the device when it is not in operation. As a countermeasure to this problem, a cushioning rubber 47 is attached to the pace 7 frame 41 as shown in Fig. 4, so that the base frame 41 shakes greatly when a large impact is applied. A method has been adopted to reduce the amount of sway when the shock absorber rubber 47 hits the mount frame 42K.However, this increases the number of parts for the shock absorber and increases the man-hours required to attach the shock absorber to the base frame, increasing costs. In addition, the shape of the pace 7 frame must be made so that the cushioning rubber can be attached, which reduces the degree of freedom in design.

記憶装置を提供する事にある。The present invention is intended to solve this serious problem.The purpose of the present invention is to reduce the volume occupied by the anti-vibration rubber, eliminate the need for a cushioning rubber, and provide vibration-resistant construction using only one type of anti-vibration rubber. The purpose of the present invention is to provide a compact data storage device with good impact resistance, high capacity, and high density recording.
本発明のデータ記憶・装置に用いられている防振ゴムは
、ベースフレーム、マウントフl/−ム、防振ゴム押え
板のそれぞれに当接する当接面を有し。The anti-vibration rubber used in the data storage device of the present invention has a contact surface that abuts on each of the base frame, the mount frame, and the anti-vibration rubber presser plate.
当接面のうち少なくとも3面に凹凸面を形成し、その内
少なくとも一面は、防振ゴム押え板と当接する当接面と

In a state where only the convex portions are in contact and vibrations and shocks are applied during data recording and reproduction, the spring constant of the vibration isolating rubber is small and the resonant frequency is low. This widens the vibration isolation frequency range. In addition, in devices that use a closed-loop servo for head positioning, the resonance point can be set at a low frequency point with high servo gain.
オフトラック量を小さく出来る。Off-track amount can be reduced.

The ratio of absorbed energy to the amount of displacement (deflection t) is large.

さTiミラえるとバネ定数が大きくなっている。A solid line 31 indicates the vibration-proof rubber characteristics of the present invention. When the external force is small, the spring constant (external force/displacement) is small, and when the displacement is equal to the convex height Ti, the spring constant becomes large.

特性を実現出来、共振周波数を低く出来る。In FIG. 1, consider, for example, the portion JK sandwiched between surfaces 11 and 13. The spring constant of the anti-vibration rubber is
(Rubber contact area/rubber height) X On one surface 11 determined by Young's modulus, the contact area of the convex part is kana 9 smaller than the working part on the 8th part, and the rubber height is TK Since it can be approximated, the spring constant can be made slightly smaller in the R portion. Therefore, by using a rubber (hard rubber) with a large Young's modulus as the vibration-proof rubber material, it is possible to realize a rubber characteristic with a small spring constant and lower the resonance frequency when recording and reproducing data.
