Optical disks started appearing in the computer market.
It is projected that they will compete favorably with
magnetic storage media in many demanding applications
like office filing and engineering data bases. In this
talk we outline the projected long term difficulties
between magnetic and optical disks and we describe some
properties of optical disks that make them appropriate
for these markets.
Based on our description we present a model for study-
ing the performance of retrieval operations from opti-
cal disks. We then describe a simple optical disk head
scheduling algorithm and we present exact and approxi-
mate analytic formulae for the evaluation of the re-
trieval cost for documents and records from an optical
disk. Finally we outline some research directions in
the area.
