Abstract
A method and apparatus for storing compressed data on DAT media. The data is stored into a standard DDS group format prior to compression, and after compression, the group is stored into a variable number of frames for recording onto the DAT media. If the compression does not meet a predetermined standard of efficiency, then the group is stored in a fixed number of frames and recorded onto the DAT media without compression.
