In order to develop good error-control coding strategies for a read/write optical disk it is necessary to know the error characteristics of the media. Since the technology is in its genesis, empirical information on the error traits is not available. It is thus necessary to base the design of coding strategies on projected behavior and similar, well-established technologies. We examine the generation of a suitable error control strategy for an optical disk buffer which is to be used for the temporary or archival storage of large quantities of data. The buffer consists of multiple, read/write, magneto-optic surfaces which are independently accessable. Information is stored in a spiral eight-bit wide track; thus an appropriate error-control code must be capable of correcting symbol and burst errors. The properties of Reed-Solomon codes, which are well known for their packet protection capabilites, are considered for such an application. Since there are multiple surfaces, we present the possibility of coding across the surfaces. With this type of coding an entire surface can be lost without destroying the integrity of the data. Intermittent operation of a read/write device such as a laser could be corrected, thus providing a graceful degradation of operation. The interaction of independent access and simultaneous read/write capabilites with the coding scheme is considered.
