Abstract
An optical data storage system utilizes optical fibers for transfer of information to and from storage media. The storage media includes magneto-optical storage disks. The optical fibers are single-mode polarization maintaining optical fibers. A single frequency laser diode provides a source of polarized light. Accordingly, a polarization state conveyed by the polarization maintaining optical fiber is accurately reproduced with reduced noise, as compared to use of a Fabry-Perot laser diode.
