ABSTRACT:
A digital audio recorder and player stores addresses of recorded audio data in at least two directories. The directories are used cyclically, address information always being read from the directory with the most recent valid address information. After a recording or editing operation, the address information read from this directory is updated, then stored in the next directory in the cycle. Each directory preferably also stores tag information identifying the directory with the most recent address information. The directories can be stored on the same digital recording medium as the audio data. This medium is, for example, a flash memory device.
