MULTICHANNEL OPTICAL RECORDING APPARATUS EMPLOYING LASER DIODES

摘要

An apparatus for recording onto and reading from an optical disk includes an array of laser diodes that emit a plurality of laser beams with each beam at the diode source spaced a distance greater than about 50 <0>m from adjacent beams. The apparatus includes a plurality of channel waveguides coupled to the plurality of laser diodes with each channel waveguide associated with a respective laser diode for directing light emitted by the diodes toward the optical disk for optical recording and for receiving reflected light from the optical disk for reading the optical disk. Each beam emanating from the channels is spaced from adjacent beams a preselected distance less than about 50 <0>m.
