Kenwood MZ-B3 manual System limitations, Symptom Cause

System limitations

The recording system in your MiniDisc recorder is radically different from those used in cassette and DAT decks and is characterized by the limitations described below. Note, however, that these limitations are due to the inherent nature of the MD recording system itself and not to mechanical causes.

The edited tracks may exhibit sound dropout during search operations.

The fragmentation of data may cause sound dropout while searching because the tracks are played at higher speed than normal playback.
