摘要： An information recording and/or reading apparatus has a base plate, a spindle motor for rotating a disk by the output shaft perpendicular to the base plate, a rotary alignment control device for determining the rotation position of a recording/reading head of a head unit about a rotary alignment axis parallel to the output shaft of the spindle motor, a linear movement guide extending parallel to the rotary alignment axis, and a support mechanism for supporting the rotary alignment control device to be reciprocally movable along the linear movement guide. An information recording and/or reading apparatus allows very easy exchange of a recording/reading head and disk, and can avoid troubles such as damage to the recording/reading head and disk during exchange.

摘要： A disk player having a self-compensating dynamic balancer which can limit internal vibrations generated by an eccentric center of gravity of a disk, and a turntable, a clamper and a spindle motor which incorporate a self-compensating dynamic balancer. The self-compensating dynamic balancer is formed integrally with rotating members in a disk player; that is, a turntable, a clamper and/or a rotor of a spindle motor. The self-compensating dynamic balancer includes at least one race which is integrally formed with the rotating member and rotates around a rotational shaft, a mobile unit which is located in the race to be capable of moving, and a cover member for covering an opening of the race. Thus, internal vibrations occurring due to the eccentric center of gravity of the disk can be effectively limited by the self-compensating dynamic balancer in which the mobile unit is disposed far away from the center of orbital rotation by a centrifugal force during rotation thereof.

摘要： A clamping device consists of a disk table for setting thereon a disk-like recording medium bearing recorded information, and a clamper which cooperates with the disk table to hold the recording medium therebetween. At least one of the disk table and the damper is formed of polypropylene at where to contact with the recording medium. If a special disk, which has a high-temperature softening film on its label surface, is clamped under high temperature conditions for a long time, and the film softens and thereafter re-solidifies as the temperature lowers, a smooth release of the recording medium is attained.

摘要： A magnetic disc unit which can restrain occurrence of flutter so as to countermeasure such a problem that the larger the rotational speed of discs, the higher the flutter, causing heat positioning errors, in order that the high rotational speed and high positioning accuracy are consistent with each other. Discs are surrounded along their outer peripheries by a shroud (outer wall) while a gap between end faces of the discs and the shroud is decreased to a predetermined distance, thereby to eliminate air pressure differential between opposite surfaces of each of the discs in order to reduce flutter.

摘要： A balancing mechanism for the spindle of a computer hard disk drive uses two, substantially flat wire clips at each end of the disk pack. The clips are designed so that one clip in each pair nests concentrically inside the other clip in the pair. Each clip is provided with a substantially identical imbalance in the installed position. If the imbalance vectors of each clip at one end of the disk pack are oriented 180 degrees apart, the resulting imbalance at that end of the pack is zero. Conversely, if the imbalance vectors are oriented at the same angle, the imbalance is maximized. Thus, the resolution of the imbalance provided by the clips is theoretically infinite between these limits, up to the precision of the clips. The orientation of the imbalance vector is controlled by the angle of the pair of clips relative to an index mark on the disk pack. The magnitude of the desired counterbalance is controlled by rotating the clips in each pair relative to each other. The cross-sectional shape of each pair of clips can be varied, and include the following examples: rectangular cross-sections having a generally flat profile, cross-sections with nesting grooves and ridges, and wire that is concave on one side and convex on the other side.

摘要翻译： 用于计算机硬盘驱动器的主轴的平衡机构在磁盘组的每一端使用两个基本扁平的线夹。 夹子被设计成使得每一对中的一个夹子同心地嵌套在该对中的另一个夹子内。 每个夹具在安装位置上具有基本相同的不平衡。 如果磁盘盒的一端的每个夹子的不平衡向量相互取向180度，则在该组件的该端部处产生的不平衡为零。 相反，如果不平衡矢量定向在相同的角度，那么失衡最大化。 因此，剪辑提供的不平衡的分辨率理论上在这些限制之间是无限的，直到剪辑的精度。 不平衡矢量的方向由一对夹子相对于盘片上的索引标记的角度控制。 通过相对于彼此旋转每对中的夹子来控制所需平衡度的大小。 每对夹子的横截面形状可以变化，并且包括以下示例：具有大致平坦轮廓的矩形横截面，具有嵌套槽和脊的横截面，以及在一侧上凹入并且在一侧上凸起的线 另一边。
