A 10 MM Thick Head Mechanism for a Stacked Optical Disk System

Not Accessible

Your library or personal account may give you access

Abstract

Optical library systems are used for applications which require large storage capacities. However, their access times are too long, sometimes exceeding 10 seconds, for active read/write uses. Recently, a stacked disk system with a head mechanism re-positionable on different disk surfaces1) have realized faster access. Nevertheless, their access times are still too long for random access jobs.
