摘要： An aligning device for a disk recording medium capable of reducing eccentricity using a simple structure, without an increase in cost, is provided. An aligning member has a tapered portion that contacts with a center hole of a disk, and fits with a guide portion that is fixed to a turntable with a sliding gap therebetween. The sliding gap between the aligning member and the guide portion is formed such that a leading end side sliding gap of the turntable in the sliding direction of the aligning member differs from a trailing end side sliding gap of the disk side in the sliding direction. The leading end side sliding gap is formed smaller than the trailing end side sliding gap. The amount of eccentricity of the disk becomes smaller according to this structure.

摘要： A clamp mechanism comprises a turntable, a plurality of chuck claws, and a driving element. The turntable is rotatably driven by a motor. A disc serving as a recording medium is placed on the turntable. The chuck claws are used to hold, that is, clamp the disc on the turntable. The driving element drives the chuck claws both in both a first direction determined to clamp the disc and a second direction determined to unclamp the disc. The driving element includes a pressing portion so that travel of the chuck claws in the first direction in cases where the chuck claws are driven in the second direction. This offers stable clamping and unclamping operations of the chuck claws to detachably hold the disc on the turntable, independently of which attitude the disc takes.

摘要： A disc clamp having centering features, and a method for centering a disc clamp on a spindle hub within a disc drive utilizes a disc clamp having a series of alignment tabs extending into an inner edge for centering the disc clamp on a motor spindle hub. Each alignment tab has an engagement face that defines a curved or chamfered surface, where the curved surface reduces disc clamp/motor spindle hub interaction when the disc clamp is installed on the spindle hub.
