DATA RECORDING/REPRODUCING APPARATUS, DATA RECORDING/REPRODUCING METHOD, PROGRAM, AND RECORDING MEDIUM

摘要

A DATA RECORDING/REPRODUCING APPARATUS FOR USE WITH A DISC RECORDING MEDIUM HAVING A PLURALITY OF EITHER CONCENTRIC OR SPIRAL TRACKS FORMED THEREON, EACH OF THE TRACKS BEING DIVIDED INTO A PLURALITY OF SECTORS IS PROVIDED. THE APPARATUS INCLUDES A SEEKING ELEMENT FOR SEEKING A TARGET TRACK; A DATA ACCESSING ELEMENT FOR ACCESSING DATA ON THE TARGET TRACK REACHED BY THE SEEK; AND AN ERROR CORRECTING ELEMENT FOR CORRECTING ERROR IN THE DATA BASED ON AN ERROR CORRECTION CODE GENERATED BY THE ERROR CORRECTING ELEMENT FOR ERROR CORRECTION PURPOSES. THE ERROR CORRECTING ELEMENT ESTABLISHES A FIRST ERROR CORRECTION CODE INCREMENT PER PREDETERMINED DATA QUANTITY, ESTABLISHES A SECOND ERROR CORRECTION CODE INCREMENT FOR A PLURALITY OF FIRST ERROR CORRECTION CODE INCREMENTS DEPENDING ON INFORMATION ABOUT STATUS ON THE DISC RECORDING MEDIUM, AND FORMS ERROR CORRECTION BLOCKS EACH CONSTITUTED BY A PLURALITY OF THE FIRST ERROR CORRECTION CODE INCREMENTS AND BY THE SECOND ERROR CORRECTION CODE INCREMENT ADDED TO THE FIRST ERROR CORRECTION CODE INCREMENTS.
