Abstract

This paper describes magnetooptical (MO) readout and recording performance improvement that increase the MO disk drive performance. In regard to readout performance, a <60-dB readout carrier-to-noise ratio is achieved for an MO disk with a polycarbonate substrate. Also, in regard to recording performance, a new MO head is presented that achieves high optical transmission efficiency (~57%) without sacrificing the readout performance. As a result, disk rotation speed can be increased, and the data transfer rate can be improved.

摘要

本文描述了磁光（MO）读出和记录性能的改进，这些改进提高了MO磁盘驱动器的性能。在读出性能方面，对于具有聚碳酸酯基板的MO磁盘，实现了<60 dB的读出载波噪声比。此外，在记录性能方面，提出了一种新的MO磁头，该磁头在不牺牲读出性能的情况下实现了高光学传输效率（约57%）。结果，可以提高磁盘转速并改善数据传输速率。
