摘要： The conventional ramp mechanism constituting a load/unload mechanism for a magnetic disk is disadvantageous for increasing a storage capacity since an outer peripheral edge of the disk is not used as a data area. In one embodiment of the invention, a disk drive has a solenoid and spring for turning a ramp mechanism about a rotating shaft. When the drive operates, since the ramp mechanism moves out from the magnetic disk by the tensile force of the solenoid, the outer peripheral edge of a magnetic head that has formerly been unusable can be used as a data read/write region, without the magnetic head interfering with the fins of the ramp mechanism. During a non-operating state of the drive and in case of a power interruption, the tensile force of the spring returns the ramp mechanism to a position at which the magnetic head can be unloaded. This construction allows the storage capacity of the drive to be easily increased without sacrificing the shock resistance of the ramp mechanism.

摘要： The positioning accuracy of a magnetic head decreases due to vibrations in the in-plane rotation mode of an HDD, which are caused by couple or disturbance occurring in seek operation, due to vibrations in the thrust mode, and the conical mode, of the spindle, which are caused by disturbance, and due to vibrations in the case thrust mode, the spindle fall mode, and the like. In one embodiment, an elastic support member includes a pillar-shaped part. The elastic support member is provided with a recess on a surface opposite to a corner of a base, and longitudinal fin projections on the upper and lower sides with respect to the recess. The base is provided at its corner with a horizontal fin that is parallel to a disk surface. The horizontal fin is inserted into the recess of the elastic support member. The longitudinal fin projections come into contact with the base, and control basic vibrational characteristics on both the upper and lower sides with respect to the horizontal fin. The pillar-shaped part is provided with a zigzag-shaped part so that the pillar-shaped part may come into contact with a frame.
摘要翻译：磁头的定位精度由于由于推力模式中的振动和主轴的锥形模式而导致的由于在寻道操作中发生的耦合或干扰而导致的HDD的面内旋转模式中的振动而降低。，这是由于扰动引起的，并且由于壳体推力模式下的振动，主轴下降模式等。在一个实施例中，弹性支撑构件包括柱状部分。弹性支撑构件在与基座的角部相对的表面上设置有凹部，并且在相对于凹部的上侧和下侧具有纵向翅片突起。底座在其角部设有平行于盘表面的水平翅片。水平翅片插入到弹性支撑构件的凹部中。纵向翅片突起与基座接触，并且相对于水平翅片控制上下两侧的基本振动特性。柱状部分设置有锯齿形部分，使得柱状部分可以与框架接触。
