Abstract

When supporting an HDA including an H/DA and an electronic control circuit board for controlling the same in a fixed frame (drive bay) of upper level apparatus by means of elastic or 'soft' fixation, counterforce of an FPC cable gives it bad influence. When rigidly securing the HDA in a translational motion direction while attaining soft fixation in a direction of rotation, the HDA is rotatably supported with its center of gravity being as the center of rotation in a soft secure/support mechanism as taught from Published Japanese Patent Application No. 8-161880 (JP-A-8161880) for example; however, in the case of employing one of commercially available general purpose HDAs, this is disposed so that a bent or curved portion of its cable is identical in position to the rotation center or placed at a nearby location of the gravity center to thereby preclude the stiffness of an FPC cable hardly affects such rotatable support mechanism. This makes it possible to minimize creation of a torque posing a bar to free rotation of the HDA, which in turn enables mounting of the general purpose HDA thereby permitting wide spread of soft securing techniques. It is possible to facilitate popularization of a scheme for mounting a magnetic disk drive into portable or mobile equipment.
