A disk cartridge, for use in a disk drive, has a shutter for opening and closing over a disk access opening. A compression spring provides a force to bias the shutter to a closed position. The spring is coupled at one end to the shutter and follows an arcuate path substantially concentric with the disk within the cartridge.

A data storage system having a disk cartridge with a rotary inner shell to permit access to a medium is disclosed. The cartridge comprises a latch disposed on an edge of the cartridge for locking the cartridge in a closed position. A flexible lever in the data storage device is adapted to engage and unlock the latch during cartridge insertion. The lever having a spring portion flexes away from the cartridge as it is further inserted into the data storage device.

A disk cartridge has two shell layers encapsulating a medium. The first layer encases the disk medium. The second layer encases the first layer. Both layers have a head access opening such that rotation of one layer relative to the other layer causes the head access openings to be aligned or misaligned. When the head access openings are misaligned the cartridge is closed. When the head access openings are aligned the cartridge is open.

A process for assembling a disk cartridge is disclosed. The process includes the steps of snapping a top shell half of the disk cartridge over a bottom shell half of the disk cartridge; adjusting the shell halves until the shell halves are in abutment contact with each other at a weld site; and directing an energy beam at the weld site until a portion of the top shell half and a portion of the bottom shell half fuse so that the top shell half is fixed to the bottom shell half. The process is repeated for each of a plurality of weld sites located on the perimeter of the disk cartridge. A process for assembling a disk cartridge is disclosed in which an energy beam is split into a plurality of split energy beams. The plurality of split energy beams are focused on a plurality of weld sites until a portion of the top shell half and a portion of the bottom shell half fuse so that the top shell half is fixed to the bottom shell half. A disk cartridge prepared by either of the above described processes is also disclosed.

A system for inserting and ejecting a cartridge from a removable media disk drive is disclosed. The system works by pushing the cartridge into the drive until a stop is reached. Thereafter, when the pushing is ceased, the cartridge is locked into position in the disk drive. To eject the cartridge, the cartridge is again pushed into the drive until a second stop is reached. Thereafter, the cartridge is ejected from the drive.
