DESC: The MZ-M200 is fully backward compatible with all minidisc recordings. Records SP/Mono/LP2/LP4 format audio to standard MD discs and uploads standard MD recordings to PC. Plus, Mac users have the ability to record in PCM, Hi-SP and Hi-LP and upload those recordings in WAV format via USB. Uploading is in no way restricted (unlimited uploads of mic, line and digital recordings are permitted).
