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 facilitat…
