Abstract
To achieve high speed overwriting on magneto-optic disks, magnetic field modulation recording using a floating magnetic head has been developed. High reliability for the removable disks can be attributed to the large head-and-disk spacing(2∼4µm), and thick coating(5∼10µm) on the disk. Characteristics of high speed overwriting were investigated at recording frequencies over 10MHz. No residual pre-recorded signal was observed after overwriting.Keywords
