Abstract

The RCA Optical Disk Jukeboxes (ODJ) delivered in 1984 and 1985 use unformatted, write-once 14-inch Du Pont media. This media can store 10 GBytes on one side of the disk. Unformatted media allows maximum utilization of the disk surface and makes it easy to use alternate types of media on the ODJ. Media formulation changes are more easily accommodated, allowing more freedom in media advancements. Because the media is unformatted, the amount of data which can be stored on the disk will vary, depending on the way it is used. Record sessions of less than 10-100 MBytes reduce the amount of data stored on the disk. This paper gives data on the media capacity vs. record session length and discusses how this impacts system integration issues. File access times, access rates and transfer rates are given for the first ODJ as delivered and for the most recent ODJ in our laboratory when using the Hyper ChannelTM interface to a VAXTM computer.
