Abstract
An apparatus and method to detect the boundary between a recorded region and a recordable region. When data is recorded on fixed length packets, with each packet comprised of a plurality of blocks, the boundary is determined by a block in which a reading error has occured and that is located at a position distant from a track head by an integral multiple of the packet length. Alternatively, when the blocks are identifiable from among a plurality of block types, the boundary is determined by using the block type of the eroneous block.
