International Classification:

G02B 2500

US Classification:

359291, 359290

Abstract:

A micro-mirror strip assembly having a plurality of two-dimensional micro-mirror structures with improved deflection and other characteristics is presented. In the micro-mirror structures, electrodes for electrostatic deflection are disposed on conical or quasi-conical entities that are machined, attached or molded into a substrate. The electrodes are quartered approximately parallel to or offset by 45 degrees from rotational axes to form quadrants. Torsion sensors are provided along the axes of rotation to control deflection of the quadrant deflection electrodes.

International Classification:

G11B007/135

US Classification:

369/112270

Abstract:

An optical data storage system utilizes optical fibers for transfer of information to and from storage media . The storage media comprises magneto-optical storage disks. The optical fibers are low-birefringence optical fibers. As compared to the prior art, a polarization state conveyed by the optical fiber is accurately reproduced with reduced noise.

International Classification:

G11B005/09

US Classification:

369047100, 369053100

Abstract:

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.

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G11B 700

US Classification:

369 59

Abstract:

A pulse width modulation (PWM) optical disk drive calibrates the write and preheat pulse patterns generated by the laser to a particular media and media condition. This is accomplished by either reading information prewritten on the media, which indicates the expected thermal interference, or by directly measuring the thermal interference from a calibration sequence recorded when new media is inserted into the disk drive. The direct measurement of thermal interference is performed by first trial writing a specific calibration sequence of marks and gaps on the media. This calibration sequence, called the E(th) sequence, is then read back and the thermal interference value, E(th), is calculated. The specific write and preheat pulse patterns are then adjusted, as a function of the calculated value of E(th), by selecting new sets of write and preheat pulse patterns. The new sets of write and preheat patterns are selected from a look-up table that correlates the correct pattern sets with the measured value of E(th).
