Compact write system for optical tape recording

摘要

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.
