چکیده

Optical disk drives provide an effective solution to the growing need for removable high-capacity storage. In this paper, we review the technology behind the optical disk drives used in IBM’s optical storage systems. The basic physics of data recording and readout and the engineering of the primary building blocks of an optical drive (the optical head, the servo system, and the data channel) are discussed. We also outline the technological directions of future optical drives as they must continue to improve in performance and capacity.

Partial-response signaling for phase-change optical data storage without electronic equalization.

We describe the application of partial-response (PR) signaling in rewritable phase-change optical data storage. No electronic filter is necessary to shape the readout signal to a certain PR target. A PR-like waveform at the output of the read channel is directly achieved by optical recording. A genetic algorithm is used to optimize the parameters for writing and therefore to minimize the differ...

High Frequency Wobbles: A Write Clock Generation Method for Rewritable DVD That Enables Near Drop-In Compatibility with DVD-ROMs

This paper presents an overview of a new method of write clock generation on rewritable DVD drives that eliminates many of the problems associated with reading rewritable disks in DVD-ROM drives. It is believed that such a format will provide tremendous benefits to the end user, making it possible to edit content on a rewritable DVD disk and then play that same disk in a conventional DVD-ROM pl...
