Claims
- 1. In a disk cartridge having a cartridge housing adapted for enclosing a disk, and having a door on said cartridge housing movable between an open position wherein, when a disk is enclosed in said cartridge, a surface of the disk is exposed to a read/write head in a disk drive to enable recording and/or reading of data recorded on said disk and a closed position wherein, when a disk is enclosed in said cartridge, the disk surface is not exposed to a read/write head, and bias means carried by said cartridge housing biasing said door to its closed position, wherein said cartridge housing is a generally flat housing having opposite first and second major sides and an edge surface, and wherein said door includes a first surface adjacent to a portion of said cartridge edge surface, the improvement comprising:
- a door opening engagement device on said first surface of said door comprising a recess on said first surface of said door, said recess being offset from the plane centered between said first and second sides to be oriented in the upper or lower portion of the door depending on the orientation of said cartridge housing.
- 2. Apparatus according to claim 1 wherein said cartridge housing has an access opening in each of said opposite sides permitting access to opposite sides of said disk, said door having first and second leg portions and a body portion arranged so that the leg portions of the door close the access openings in both sides of said cartridge housing when said door is in its closed position, said body portion extending over a portion of the edge surface of said cartridge housing, said recess being in said body portion.
- 3. Apparatus according to claim 2 wherein the door has one open position and said recess is engagable by a door opening mechanism in the disk drive to permit the door to be moved from its closed to its open position regardless of the orientation of the cartridge housing.
- 4. Apparatus according to claim 1 further including lock means comprising a lock button mounted to a resilient support, said resilient support biasing said lock button into said recess when said door is in its closed position to lock said door in its closed position, said lock button being engagable by a door opening mechanism in the disk drive to force said button out of said recess to unlock said door.
- 5. Apparatus according to claim 1 wherein the door has one open position and said recess is engageable by a door opening mechanism in the disk drive to permit the door to be moved from its closed to its open position regardless of the orientation of the cartridge housing.
- 6. Apparatus according to claim 5 further including lock means comprising a lock button mounted to a resilient support, said resilient support biasing said lock button into said recess when said door is in its closed position to lock said door in its closed position, said lock button being engagable by said door opening mechanism to force said button out of said recess to unlock said door.
- 7. A disk cartridge, as claimed in claim 1, further comprising:
- means for slidably attaching said door to said cartridge housing wherein said door is permitted to slide in a direction substantially parallel to said first major side.
- 8. A disk cartridge, as claimed in claim 7, wherein:
- said means for slidably attaching said door comprises a slider partially received in a cavity formed by at least one rail formed on an inside surface of said cartridge housing.
- 9. A disk cartridge for enclosing a disk usable in a disk drive having a read/write head, the cartridge comprising:
- a housing adapted for enclosing a disk by having a space therein, said space being substantially disk shaped, said housing being generally flat and having opposite first and second major sides and an edge surface;
- a door on said housing movable between an open position wherein said space is exposed to the read/write head in the disk drive and a closed position wherein at least a portion of said door is between said space and the read/write head, and wherein said door includes a first surface adjacent to a portion of said cartridge edge surface and having a recess therein; and
- lock means comprising a button and means for urging said button in a first direction wherein, when said door is in said closed position, said button extends into said recess for preventing opening the door.
- 10. A disk cartridge for enclosing a disk usable in a disk drive having a read/write head and also having unlocking means, the cartridge comprising:
- a housing adapted for enclosing a disk by having a space therein, said space being substantially disk-shaped, said housing being generally flat and having opposite first and second major sides and an edge surface;
- a door on said housing movable between an open position wherein said space is exposed to the read/write head in the disk drive and a closed position wherein at least a portion of said door is between said space and the read/write head, and wherein said door includes a first surface adjacent to a portion of said cartridge edge surface and having a recess therein; and
- lock means comprising a button and means for urging said button in a first direction wherein, when said door is in said closed position, said button extends into said recess for preventing opening the door and wherein said lock means is engagable by the unlocking means in the disk drive to force said button out of said recess for unlocking said door.
