Patent ID: 6959445

Claim:
A disc drive apparatus comprising: a rotation drive mechanism configured to drive or rotate an optical disc, which has a disc table onto which the optical disc is to be placed, and a motor for rotating the disc table; a clamp member configured to clamp the optical disc jointly with the disc table, the optical disc being placed on the disc table; a hold mechanism configured to rotatably hold the clamp member, which causes the clamp member to shift toward the disc table with an axis of the clamp member being substantially perpendicular to a top surface of the disc table when the clamp member clamps the optical disc jointly with the disc table, and causes the clamp member to shift away from the disc table with the axis of the clamp member being inclined at an obtuse angle against the top surface of the disc table in the direction of the hold mechanism when the clamp member releases the clamp state of the optical disc clamped by the clamp member and the disc table; wherein the hold mechanism has a hold section configured to hold the clamp member, and a hold arm by which the clamp member is rotatably held and the hold section is formed in a tapered shape such that its thickness is reduced gradually from the basal portion to the end thereof.
