Paper
A Review of Some Recent Work in Magnetooptical Recording
Abstract
This ‘paper will review recent progress in disk recording with GaAs laser transducers and magnetooptical media. Reading and writing experiments have been performed at frequencies up to 5 MHz with a cryogenic disk assembly using Fe-EuG as the storage media. Experiments have been done with other magnetooptical materials such as intermetallics for room temperature operation. The efficiency, polarization, and lifetime of batch fabricated GaAs lasers will be described. Copyright © 1973 by The Institute of Electrical and Electronics Engineers, Inc.
