- whereby, said link actuator travels along said groove means to engage said detent means during longitudinal insertion of said disk cartridge into the cartridge-receiving receptacle of the disk drive, and continued longitudinal insertion movement of said disk cartridge into the cartridge-receiving receptacle causes said link actuator to pivot away from said first position and move generally transverse along said track to move said panel means from the closed position to the open position, the direction of said transverse movement having a component opposite to said direction of urging of said first biasing means and said direction of said transverse movement having a component opposite to said direction of urging of said second biasing means during at least a first portion of said transverse movement.
- 7. Apparatus according to claim 6 wherein said direction of transverse movement has a component opposite to the direction of urging of said second biasing means associated with said panel means for urging the panel means to the closed position and said direction of transverse movement has a component in said direction of urging of said first biasing means, during a second portion of said transverse movement.
- 8. Apparatus according to claim 6 wherein said panel means comprises a pair of doors, a wing attached to each said door and extending generally transverse thereto, said channel means comprising a pair of channels each forming a generally transverse track, said slot means comprising a slot along each said track through said casing and said groove means comprising a pair of grooves each extending between a front edge of said casing and one of said slots, said detent means comprising a detent on each wing.
- 9. Apparatus according to claim 8 further including bias means associated with said panel means for urging the panel means to the closed position.
- 10. Apparatus according to claim 9 wherein said bias means comprises a wire spring mounted to said casing and contracting each of said doors.
- 11. Apparatus for providing access to a disk comprising, in combination:
- a disk drive having a cartridge-receiving receptacle within which a disk cartridge is inserted in a generally longitudinal direction, support means pivotally supporting a link actuator in said receptacle;
- a disk cartridge having a casing, a disk inside the casing, means defining an access window in said casing, channel means within said casing forming a track generally transverse to said longitudinal direction, slot means extending along said track and through said casing, groove means in said casing extending longitudinally from an edge of said casing to said slot, and panel means mounted to said channel means for movement along said track between an open position to allow access to said disk through said window and a closed position to substantially prevent such access, said panel means having detent means open to said slot means to permit engagement thereof by said link actuator to move said panel means between its closed position and its open position, said detent means being open to said groove means when said panel means is in its closed position; and
- an arcuate slot formed in said support means, said link actuator includes a column extending toward said cartridge through said arcuate slot, whereby the column extends through said groove means to engage the detent means during insertion of said disk cartridge into said cartridge-receiving receptacle and said link actuator pivots so that said column tracks arcuately in said arcuate slot while tracking transversely along said slot during continued insertion of said disk cartridge; and whereby said link actuator travels along said groove means to engage said detent means during longitudinal insertion of said disk cartridge into the cartridge-receiving receptacle of the disk drive, and continued longitudinal insertion movement of said disk cartridge into the cartridge-receiving receptacle causes said link actuator to pivot and move generally transverse along said track to move said panel means from the closed position to the open position.
