Data recording apparatus and data reproducing apparatus

摘要

A data recording device and a data reproducing device for appending data in a data storage device without requiring that data be read up to the last group directly before an end-of-data area. A system controller controls a recording data processing system, a data recording/reproducing unit, a playback data processing system and a tracking control system for recording the identification information of the last group in an end-of-data (EOD) area and for reading out the identification information of the last group from the EOD area.
