ABSTRACT:
A disc apparatus includes rotatable discs each having a recording disc surface or surfaces, a head for recording and reproducing information to or from the disc, and an actuator for moving the head along the surface of the disc. The disc, the head, the actuator, and the like are accommodated in a rectangular housing which is supported on a frame of the apparatus by four dampers arranged at four corners of the housing. The center of gravity of the housing is located nearer one corner with respect to the other corners. The spring constant of the damper located at the corner which is at the greatest distance from the center of gravity is smaller than the spring constants of the other dampers.
