Abstract

Cartridge removability is one of the most important features offered by the optical disk drive. To take advantage of this feature, it is desirable to have a common tracking and data format. It is the intent of this paper to provide a performance comparison, in terms of data capacity and transfer rate, of the various codes, including (2,7), (1,7) for continuous composite servo(CCS) and RZ, NRZ, four-out-of-fifteen(FOOF) and four-out-of-eleven(distributed block format, DBF) for sample servo(SS) . It is hoped that this comparison will be useful for the selection of a common data encoding scheme.
