Abstract
A reproducing apparatus compatible with both CD and MD. First and second cartridge holding members are rotatably supported by a cover unit between a position where MD is held on a turntable and a position where the holding members are retracted not to contact CD held between the turntable and a clamper. The clamper is movable between a position where CD is clamped to the turntable and a position where the clamper is retracted not to contact MD held on the turntable. An optical pickup movably supported by a main unit reproduces both CD and MD.
Claims11
An optical disk recording/reproducing apparatus for recording and reproducing a stand alone first optical disk and a second optical disk housed in a cartridge, the diameter of said first optical disk being larger than any dimension of the cartridge of said second optical disk, comprising:
- a turntable and a pickup operative with said first and second optical disks set at a recording/reproducing position on the top surface of said turntable;
- holding means (7, 8) for holding the cartridge of said second disk to set said second optical disk at the recording/reproducing position and being retractable in the direction parallel to the top surface of the turntable, said first optical disk being free from mechanical interference from said holding means when said first optical disk is set at the recording/reproducing position;
- and
- a clamper (12) for abutting against said turntable through said first optical disk to clamp said first optical disk to said turntable when said first optical disk is reproduced and being retractable in the direction parallel to the top surface of said turntable, the cartridge of said second optical disk being free from mechanical interference from said clamper when said cartridge is set at the recording/reproducing position when said second optical disk is reproduced.
An optical disk recording and reproducing apparatus for recording/reproducing a stand alone first optical disk and a second optical disk housed in a cartridge of a generally rectangle shape, the diameter of said first optical disk being larger than any dimension of the cartridge of said second optical disk, comprising:
- a housing having a top, a bottom, and at least one linear side surface extending between said top and said bottom;
- a turntable and a pickup operable with said first and second optical disks set at a recording/reproducing position on the top surface of said turntable;
- and
- holding means (7, 8) for holding between two holding bars (7a, 8a) the opposite sides of the rectangular cartridge of said second disk set at the recording/reproducing position,
- wherein said holding bars holding the rectangular cartridge of said second optical disk are aligned at nearly 45.degree. to said at least one linear side surface so that the opposite sides of the held cartridge are at nearly 45.degree. to said at least one linear side surface and said pickup is arranged to travel in a direction aligned at an angle of nearly 45.degree. to said at least one linear side surface during recording/reproducing operations.
