Abstract

We developed a 5 inch form factor magneto-optical disk drive with overwrite and real-time verification functions. A 2.1 MB/s data transfer rate for both reading and writing and an average seek time of less than 35 ms have been achieved. The 3-beams drive uses 130 mm ISO-standard magneto-optical disks. This high-performance magneto-optical disk drive provides high-speed operation and low-cost storage and is suitable for high-end systems such as optical libraries and image-data processing systems which require a high transfer rate and huge data capacity.
