US Classification:

713176, 713187, 713189, 713193, 705 57

Abstract:

An extremely secure method for keying source contents to a source storage medium provided to prevent use of unauthorized copies at minimal cost. The host processor combines a unique, immutable and verifiable physical attribute of a hard disk drive, i. e. , the drive's defect list, with the content to be secured to write a corresponding fingerprinted encrypted content on a source medium. When a local processor wants to use the sanctioned source content, the fingerprinted content is read from a local storage medium. The local processor then decrypts and separates the defect list out of the source content and reads the local storage medium defect list. If the decrypted defect list matches the local storage medium defect list, then the local processor recognizes the local sanctioned medium and continues processing the source contents. Otherwise, a non-matching defect list indicates an unauthorized copy from the source to the local storage medium.

US Classification:

720615, 369 3042, 369 3049

Abstract:

Embodiments provide methods and systems for handling optical discs in a media library appliance and for replacing optical drives in the field. In one embodiment, the media library appliance comprises optical disc handling robotics developed for slim form factor slot load drives in a vertical orientation located on both sides of the robotics within a 19 inch rackable appliance. On the system level, the optical disc storage system provides modularity and scalability. The drives reside in field replaceable units (“FRUs”) that are oriented vertically on a horizontal backplane. The disc handling robotics access discs on each side stored in horizontal stacks within large disc cartridges. A small disc shuttle cartridge attaches to a large disc cartridge to provide a means to import and export a smaller number of discs from the disc cartridge.

US Classification:

360104

Abstract:

A head suspension has an integrated multi-layer trace conductor array for supporting and electrically interconnecting a read/write head to electronic circuitry in a disk drive. The trace conductor array includes an integrally formed electrical shield which may be grounded or ungrounded and formed to have a depth greater than a skin effect depth at a frequency of an interfering wave front.
