International Classification:

G02B 2608

US Classification:

359210

Abstract:

The present invention provides a read-write head for an optical tape recorder comprised of a synchronized scanning transmissive polygon and rotating lens wheel. The transmissive polygon is a multi-sided piece of transparent optical quality material for displacing a through transmitted collimated read or write light beam. The lens wheel comprises a unitary disk-shaped piece of optical quality material having a plurality of individual lenses precision molded or diamond point turned therein for focusing the through transmitted and displaced read or write light beam onto a recording media. The polygon is rotated to translate the displaced beam for scanning along a linear path aligned with an arcuate path followed each successive lens on the rotating lens wheel. The rotation of the polygon and lens wheel are synchronized such that each scan of the displaced beam along the linear path coincides with the movement of a lens along the arcuate path to trace out a data track on the recording media. A pair of beam expanders are also provided in the read-write head as a demagnification-magnification system around the transmissive polygon to improve system performance by narrowing the diameter of the beam transmitted through the polygon.

US Classification:

369 97

Abstract:

A write module for an optical tape recorder for optically writing a data signal on light sensitive recording media. The write module comprises a rotated linear edge emitter diode array or vertical cavity emitter diode array comprising a plurality of emitter diodes. The diodes emit a plurality of write beams for writing the data signal on the recording media in a plurality of data channels. An actuator subsystem focuses and positions the write beams on the recording media. The rotation angle of the diode array is a predetermined angle to provide a predetermined separation distance between adjacent data channels. Each write beam is modulated by a designated portion of the data signal to generate a plurality of data signal modulated write beams to optically record the data on the recording media. The data signal modulating each write beam is delayed by a predetermined time value for writing a word of the data signal in adjacent data marks along a line transverse to the length of the data channels.

International Classification:

G11B 700

US Classification:

369 49

Abstract:

The optical tape recorder of the present invention is capable of archiving data at rates in excess of 400 megabits per second by concurrently writing or reading a plurality data tracks in each data trace. A read-write module outputs an illumination beam comprised of combined multiple write beams (channels), a read beam and an autofocus beam. Optics within the read-write module spatially combine and accurately position the plurality of beams with respect to each other to form the multi-beam illumination beam. A read-write head comprised of a synchronized scanning transmissive polygon and rotating lens wheel scans the multi-beam illumination beam across a recording media to read or write multi-channel data tracks. An autofocus system is also included to ensure that the multi-beam illumination beam is accurately focused on the recording media.

Abstract:

An electronically controlled, programmable searchlight (1), particularly useful for mounting on helicopters. The searchlight (1) uses a digital electronic control circuit (30) in conjunction with rotary potentiometers (32), (34) to control movement of the searchlight (1). Adjustable trimpots (22) are employed to provide the searchlight (1) with preset positions, each preset position having an easily alterable operating envelope. The searchlight (1) may have light sources (50, 52) of varying type, which may also be controlled by the electronic control circuit (30).
