Paper Abstract

A 10-mm-thick head mechanism for a 30 GB, multi-head type stacked optical disk system has been developed. A pair of linear brushless motors are utilized as the coarse actuator, and a 2D motion lens actuator is utilized as the fine one. The average access time is 150 ms. The track following characteristics are tested. The tracking error is 0.03 micrometers in amplitude with a 3600 rpm, 254 mm diameter disk.
