ABSTRACT:
A tape data recording and reproducing system is disclosed which has an over-writing capability which can result in previously recorded data continuing to exist on the tape after the over-writing has been completed. The present invention uses cyclical redundancy check data that is normally recorded with the data to determine if the data recovered during reproducing is valid data.
