Apparatus for recording data and statically storing and recording supervisory information representing contents of the data on a recording medium

摘要

A recording apparatus is provided for recording data in a recording region of a recording medium and information representing contents of said data recorded in the recording medium. The apparatus includes: a recording system for recording the data and information in the recording medium; a non-volatile memory for storing the contents of the data recorded in the recording medium; and a controller for renewing the information and storing it in the non-volatile memory at a certain time interval, to thereby facilitate a backup system and to suppress cancellation of the recorded data even upon a power suspension.
