Optical disk drive
First Claim
1. An optical disk drive of the type utilizing an optical disk cartridge formed by an optical disk mounted about a hub within an enclosure, comprising:
- a chassis;
a drive spindle adapted to engage the hub of the optical disk;
a drive motor for rotating the drive spindle;
pan means movably mounted with respect to the chassis for receiving and supporting the optical disk cartridge;
a handle having a load position, a run position, and a spin-down position;
linkage means coupling the handle and the pan means for moving the pan means with respect to the chassis between a load/eject position at which the cartridge can be inserted into and removed from the pan means when the handle is in its load position, and a run/spin-down position at which the hub of the disk is engaged with the drive spindle when the handle is in its run and spin-down positions; and
control means responsive to the position of the handle for activating the drive motor when the handle is in the run position, and for deactivating the drive motor when the handle is in the spin-down position.

Abstract
An optical disk drive of the type adapted to use an optical disk cartridge formed by an optical disk mounted about a hub within an enclosure. When inserted into the optical disk drive, the cartridge is received and supported by a pan. A control handle for controlling the disk drive can be rotated between a load position, a run position, a spin-down position, and an eject position. The handle is coupled to the pan by a linkage. When the handle is rotated to either its run or spin-down positions, the linkage positions the pan at a run/spin-down position at which the hub of the disk is engaged with a drive spindle. When rotated to either its load or eject positions, the linkage causes the pan to be in a load/eject position at which the cartridge can be inserted into or removed from the pan. The position of the handle is detected by optical sensors which provide signals representative thereof to control circuitry. The control circuitry activates a drive motor when the handle is in its run position, and deactivates the drive motor when the handle is moved to its spin-down position. A spin-down interlock mechanism is interfaced to the control circuitry and permits the handle to be rotated from the run position back to the load and eject positions only after a predetermined spin-down time period has elapsed after the handle has been rotated to the spin-down position. The cartridge is ejected from the disk drive when the handle is rotated to its eject position.

18. An optical disk drive of the type utilizing an optical disk cartridge formed by an optical disk mounted about a hub within an enclosure, comprising:
-
a chassis; a drive spindle adapted to engage the hub of the optical disk; a drive motor for rotating the drive spindle;
pan means movably mounted with respect to the chassis for receiving and supporting the optical disk cartridge;a handle having a load position, a run position, and a spin-down position; linkage means coupling the handle and the pan means for moving the pan means with respect to the chassis between a load/eject position at which the cartridge can be loaded into and removed from the pan means when the handle is in its load position, and a run/spin-down position at which the hub of the disk is engaged with the drive spindle when the handle is in its run and spin-down positions; sensor means for sensing the position of the handle; spin-down interlock means responsive to interlock signals for controllably preventing movement of the pan means from the run/spin-down position to the load/eject position; and control means responsive to the sensor means for activating the drive motor when the handle is in its run position, deactivating the drive motor when the handle is in its spin-down position, and providing interlock signals causing the spin-down interlock means to permit movement of the pan means from the run/spin-down position to the load/eject position after the handle has been moved from the run position to the spin-down position and a predetermined spin-down time period has elapsed. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
