A non-woven fabric liner comprising a plurality of bonded fibers is attached to the inner surface of one of the upper and lower shells of a disk cartridge. A main body of the fabric liner lies against the inner surface of the shell and is spaced a predetermined distance from a corresponding surface of the storage media within the cartridge. A region of the fabric liner is subjected to a fuzzing process in which the bonded fibers in that region are loosened to form a region of upstanding fibers that extend from the main body of the liner to the surface of the disk. The upstanding fibers wipe the surface of the disk while the main body of the liner remains spaced from the disk, thereby reducing drag.

A disk cartridge comprises a rotatable disk having upper and lower surfaces and an outer casing for rotatably housing the disk. The casing comprises upper and lower shells that mate to form the casing. Each of the upper and lower shells has an inner surface disposed in facing relation to a respective surface of the disk. The cartridge has a head access opening on its front peripheral edge, and the upper and lower shells have grooves formed therein to provide sufficient space for the magnetic heads of a disk drive to move across the surface of the disk. A non-woven fabric liner comprising a plurality of bonded fibers is attached to the inner surface of one of the upper and lower shells. A main body of the fabric liner lies against the inner surface of the shell and is spaced a predetermined distance from the corresponding surface of the disk. A region of the fabric liner is subjected to a fuzzing process in which the bonded fibers in that region are loosened to form a region of upstanding fibers that extend from the main body of the liner to the surface of the disk.

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.
摘要:
A storage media is disclosed and comprises a storage body and a readable indelible mark formed in the body such that portions thereof are indelibly altered. The mark is read by writing first data to the body in the region of the mark, and reading second data from the body in such region. The written first data is not accepted where the portions of the body are indelibly altered. Accordingly, the read second data corresponds to the written first data with segments thereof missing. The missing segments of the first data correspond to the portions of the body indelibly altered. In a preferred embodiment, the storage media comprises a magnetic rotatable disk having a substantially planar substrate and a magnetizable layer deposited thereon. The reading and writing are therefore performed magnetically.

Data on a master is read into a master image file, and the master image file is manipulated to include a benchmark comprising tracking and verification information tied to at least a portion of the master image file. Thus, a copied-to storage media as copied from the master image file also includes such benchmark, a data alteration of the master image file causes a mis-match with regard to the benchmark in such master image file, and a data alteration of the copied-to storage media also causes a mis-match with regard to the benchmark in such storage media as copied from such master image file. The benchmark may include a part identifier and a security identifier.
