Paper Abstract

Magneto optical (MO) disks have shown great advantages in performance, reliability, price per bit, portability, rewrite cycles, high-density recording, and achieve life. For a 3.5' ISO standard MO media, the capacity of 1X-density disks is 128 MB, and 5X density disks have 540 MB/640 MB capacity, with track and bit density increased. Media testing is very important in research and manufacture of the disks. A media testing system for the characteristics of the recording layer of the 5X capacity MO disks is introduced in this paper. Many features and techniques are discussed such as to achieve high accuracy testing, flexibility to upgrade the system.
