摘要： In a clamp mechanism, an adapter, and an optical disc apparatus for compatibly playing back the MD and CD having different centering hole diameters and reference heights, a first clamp mechanism has a taper cone section for both an MD and a CD, while a second clamp mechanism has an MD turntable and a CD clamper which is driven in contact with the MD turntable while clamping the CD. The adapter is a disc which has a hole having the same inner diameter as that of the centering hole of the MD and a thickness of 0.8 mm, the adapter to be attached to the CD. A first optical disc apparatus has an MD spindle motor and a CD spindle motor, and an optical system including an objective lens is arranged on a straight line that connects both the spindle motors. A second optical disc apparatus has a spindle motor having an MD turntable and a CD turntable at both its ends.

摘要： An optical disc clamp mechanism that is capable of selectively playing back either of a compact disc or a mini disc. The clamp mechanism includes a circular disc receiving section for contacting a reference surface of either of the compact disc or the mini disc and further includes a magnetic clamp unit for clamping the mini disc by magnetic attraction with a magnetically attractable member of the mini disc. A first conical or spherical taper cone portion for engaging the center hole of the mini disc is mounted to the disc receiving section and a second conical or spherical taper cone portion for engaging the center hole of the compact disc is mounted to the disc receiving section. The first taper cone portion is located inwardly of the second taper cone portion and protrudes from the second taper cone portion in the axial direction. The magnetic clamp unit further includes a stopper element for preventing detachment of the first and second taper cone portions from the disc receiving section. Accordingly, the optical disc clamp mechanism independently affects the centering of a mini disc and a compact disc to allow either of the discs to be centered.
