摘要： A rotary information recording/reproducing apparatus has a carriage rotatable by the first and second driving coils about an axis that moves an information recording/reproducing head radially to an associated recording disk for head positioning relative to the disk. The angle between a line connecting the center of the first driving coil and the center of the carriage pivot shaft and a line connecting the head and the center of the carriage pivot shaft is set to be not greater than 90 degrees while the angle formed between the first and second driving coils about the center of the carriage pivot shaft is within the range of from 100 degrees to 150 degrees, whereby reduction in the size and thickness of the apparatus can be achieved. A magnet-yoke assembly, which is subject to a reaction force, is mounted to a base by sheet springs and reaction-force damping members interposed therebetween so that the magnet-yoke assembly is independent from and infinitesimally rotatable relative to the base. The provision of the two driving coils and the reaction-force damping members effectively prevents the carriage pivot system and the disk spindle from being excited by the reaction force to thereby assure a high-speed and highly-accurate head positioning.
摘要翻译：旋转信息记录/再现装置具有可绕第一和第二驱动线圈旋转的托架，该托架围绕将信息记录/再现头径向移动到相关联的记录盘的轴线相对于盘进行头部定位。连接第一驱动线圈的中心的线与滑架枢轴的中心之间的角度以及连接头部和滑架枢轴的中心的线被设定为不大于90度，同时形成在围绕托架枢轴的中心的第一和第二驱动线圈在100度至150度的范围内，从而可以实现装置的尺寸和厚度的减小。受到反作用力的磁轭组件通过板簧和反作用力阻尼构件安装到基座上，使得磁轭组件相对于基座独立于和无限可旋转。提供两个驱动线圈和反作用力阻尼构件有效地防止滑架枢转系统和盘主轴被反作用力激励，从而确保高速和高准确的头部定位。

摘要： A magnetic disk system utilizes both of voice coil motor and a piezoelectric element provided on a head supporting arm to precisely position a head to a predetermined position on a disk. The piezoelectric element is built in the distal end portion of the head supporting arm and is restricted in respect of its movement by a resilient mechanism which has low rigidity in the driving direction of the piezoelectric element and high rigidity in the other directions. The resilient mechanism is formed by pairs of doubled parallel leaf springs so arranged that each pair is disposed on either side of the piezoelectric element.

摘要： An object of the present invention is to restrain the rigid body rotational vibration of a magnetic disc apparatus caused by the driving reaction force of a head in order to position the head quickly and precisely and to reduce the sizes of the magnetic disc apparatus. According to this invention, a dynamic damper having a natural frequency equal to the rigid body rotational frequency of the magnetic disc apparatus is provided in at least one of the four corners inside or outside a housing of the magnetic disc apparatus. The dynamic damper comprises a weight member and bar-like members acting like springs, and has an angled shape so as to meet the form factor standard sizes for magnetic disc apparatuses.
