    摘要： A magneto-optical (MO) data storage system has a flying optical head supported over a MO storage medium, the flying head having channels or grooves formed therein and optical elements disposed within the grooves for directing an incident light beam to the storage medium and for receiving a reflected light beam from the storage medium. The flying head may comprise a two-piece assembly comprising a slider body which flies over the surface of the storage medium, and a separate optics mounting block formed to receive the optical elements and to be supported on the flying head. Preferably, the slider body is L-shaped and provides an angled surface for receiving a micro-machined mirror aligned with optical elements on the optics mounting block and controllable for deflecting the light beam to and from the storage medium.

    摘要： An optical disk data storage system uses two lasers to write data on the disk, preferably using pulse width modulation (PWM). The lasers direct two independently controllable laser beams to the disk to form two spots that are spaced apart a fixed distance along the data track. Each laser is independently controlled by a modulator that causes the laser to emit the laser beam in a highly pulsed manner. The two laser beams can be simultaneously and independently pulsed along a single track and each beam may be pulsed on any given write clock period and at any of several different power levels. The pulsed lasers write spots of substantially the same size on the disk. The PWM run lengths are recorded on the disk as marks comprising either a single isolated spot or a series of contiguous or overlapping spots. The pulsing of the two lasers is synchronously interleaved so that either adjacent marks (mark-interleaved writing) or adjacent mark edges (edge-interleaved writing) are alternately written by the two lasers. In this manner, an amount of time elapses between the writing of successive marks or mark edges, thereby significantly reducing the effect of thermal buildup by allowing time for the data layer in the optical disk to cool.

    摘要： A battery-operated, hand-held disc drive for an optical data storage disc contains a radio transceiver. Data read from the disc, for example a game or movie, are delivered to the transceiver and transmitted, preferably using a WiFi protocol, to a host device, such as a smartphone, PDA, ultra-light tablet or notebook computer, or digital TV. Preferably, the compression factor of the data on the disc and the transfer rate of the data from the disc drive to the host device are set such that that disc drive has a low duty cycle, thereby conserving battery power while providing the user with an extended usage period. To provide a high-quality experience, the data on the disc are compressed using a highly efficient data compression algorithm such as MPEG-4.

    摘要： A format for accessing content such as a full-length move from an optical disc uses an XML description file stored on the disc to generate one or more screens that a user employs to access the content. The decoding requirements of a hardware or software player are reduced by discarding specific elements of an encoding standard such as MPEG4 that is used to encode the content on the disc. The maximum average and peak bitrates at which the data is transferred are limited to further reduce the demands on the player.
