Abstract
Abstract A protective cartridge for a data storage disk (e.g. an optical disk) includes a retainer mechanism for restricting longitudinal movement of a disk/carrier assembly within the cartridge interior. Such mechanism preferably comprises a flexible, cantilever-mounted leaf spring having a lip which is adapted to engage a trailing edge of a disk-carrier after such carrier has entered the cartridge through a pivotably mounted cartridge door. To allow extraction of a retained disk-carrier from the cartridge, the retainer is located so it is engaged and moved to a non-retaining position by the cartridge door as the latter moves from a closed to an open position.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
129 words
Carrier-retaining apparatus for limiting movement of a data storage disk-carrier within a protective cartridge, such cartridge comprising a box-like container having a movably mounted door through which a disk-carrier can enter and exit the cartridge, said apparatus comprising: a carrier-retainer member mounted within said container for movement between (a) a retaining position in which said member will engage a disk-carrier that has fully entered the container through such door and prevent such disk carrier from moving in a reverse direction, toward such door, and (b) a non-retaining position in which said member is spaced from a disk-carrier located within such container, said member being movable from said retaining position to said non-retaining position in response to movement of the cartridge door from a closed position to an open position.
Claim 2
Dependent Claim
129 words
Carrier-retaining apparatus for limiting movement of a data storage disk-carrier within a protective cartridge, such cartridge comprising a box-like container having a movably mounted door through which a disk-carrier can enter and exit the cartridge, said apparatus comprising: a carrier-retainer member mounted within said container for movement between (a) a retaining position in which said member will engage a disk-carrier that has fully entered the container through such door and prevent such disk carrier from moving in a reverse direction, toward such door, and (b) a non-retaining position in which said member is spaced from a disk-carrier located within such container, said member being movable from said retaining position to said non-retaining position in response to movement of the cartridge door from a closed position to an open position.
Claim 3
Dependent Claim
17 words
The invention as defined by claim 1 wherein said carrier-retaining member is biased towards said retaining position.
Claim 4
Dependent Claim
91 words
The invention as defined by claim 1 wherein said carrier-retaining member comprises an elongaged leaf spring which is mounted in a cantilever manner to a supporting surface within the container, said leaf spring having a carrier-retaining lip which is adapted to engage and retain a carrier located within the container, said leaf spring being deflectable by the cartridge door from a normal carrier-retaining position in which said lip will engage and retain a carrier located within the container to a carrier-releasing position in which said lip is spaced from such carrier.
