Abstract
An optical disk drive which decreases unit costs and reduces the size of a product. The optical disk drive includes a frame, a base chassis rotatably installed on the frame, a spindle motor and a pick-up device installed on the base chassis, a tray moving into and out of the frame when a disk cartridge is mounted on the tray, a loading device for operating the tray and the base chassis, and a disk cartridge recognizing device for sensing whether or not recognition holes formed through a disk cartridge case are opened or closed to display data of the disk cartridge. The disk cartridge recognizing device includes switches fixed to a front part of the frame, and a switch operating portion for operating the switches according to whether or not the recognition holes are opened or closed.

An optical disk drive comprising:
- a frame;
- a base chassis rotatably installed on the frame;
- a spindle motor and a pick-up device installed on the base chassis;
- a tray for moving into and out of the frame when a disk cartridge is mounted on the tray;
- a loading device for operating the tray and the base chassis;
- and
- a disk cartridge recognizing device for sensing whether or not recognition holes formed through a disk cartridge case are opened or closed,
- wherein the disk cartridge recognizing device includes switches fixed to a front part of the frame, and a switch operating portion for operating the switches according to whether or not the recognition holes are opened or closed.
A disk cartridge recognizing device for use in an optical disk drive that receives a disk cartridge with recognition holes on a tray that moves into and out of a frame of the optical disk drive, the disk cartridge recognizing device comprising:
- an elastic unit installed on the tray, the elastic unit having pushing protrusions on one side, the pushing protrusions corresponding to the recognition holes in the disk cartridge so that they are pressed when the recognition holes are closed;
- and
- interlocking units located on the frame, the interlocking units having switches operated by the elastic unit when the pushing protrusions are pressed.
A disk cartridge recognizing device for use in an optical disk drive that receives a disk cartridge with at least one recognition hole on a tray that moves into and out of a frame of the optical disk drive, the disk cartridge recognizing device comprising:
- an elastic unit installed on the tray, the elastic unit having at least one pushing protrusion on one side of the elastic unit, the pushing protrusion corresponding to the at least one recognition hole in the disk cartridge so that the pushing protrusion is pressed when the at least one recognition hole is closed;
- and
- an interlocking unit located on the frame, the interlocking unit having a switch that is operated by the elastic unit when the pushing protrusion is pressed.
