摘要： The present invention is related to a data storage device capable of restricting access to data storage or retrieval when a first code is incompatible with a second code. The data storage device comprises (a) a data storage media having a data storage region; and (b) a controller adapted to compare a first code with a second code and to restrict access to a portion of the data storage region of the data storage device if the first code is incompatible with the second code.

摘要： A rotatable storage media includes a first data segment stored in first tracks and a second data segment stored in second tracks. The first tracks include a first start track and a first end track, and the second tracks include a second start track and a second end track. The first data segment starts in the first start track at a start rotational phase, ends in the first end track at an end rotational phase, starts in adjacent first tracks at start rotational phases offset by an intra-segment rotational skew angle and ends in adjacent first tracks at end rotational phases offset by the intra-segment rotational skew angles. The second data segment starts in the second start track at the start rotational phase, ends in the second end track at the end rotational phase, starts in adjacent second tracks at start rotational phases offset by the intra-segment rotational skew angle and ends in adjacent second tracks at end rotational phases offset by the intra-segment rotational skew angle. Furthermore, the first and second data segments are radially coherent, and the start and end rotational phases are offset by an inter-segment rotational skew angle that is greater than the intra-segment rotational skew angle.

摘要： An embedded system which stores, controls and retrieves real-time digital signals is configured as a programmable and reconfigurable embedded system. The embedded system interface is capable of handling in real time both continuous and irregular signal formats, such as Digital Video (DV) and MPEG, and stores the received signal in a format optimized for its storage medium. Upon retrieval, the signal is reconstituted back to its original format. In one example, the embedded system can receives and retrieve multiple, simultaneous digital signal data streams for a variety of digital equipment, such as digital video recorders.
