Abstract
In a tape drive used for storing computer data, both record boundary data and data separation commands, such as Write File Mark commands, are encoded with codewords to form a continuous, encoded data stream. In such a tape drive, a tape drive interface receives the record data and data separation commands and, transmits the record data to a tape drive formatter to encode the record data into a continuous encoded data stream and signals the formatter when data separation commands are received. In response to signals from the tape drive interface, the formatter generates control codewords and embeds them into the continuous encoded data stream, and the data stream is stored in a buffer.
