Abstract
In a system recording compressed video and audio signals or computer user data on a disk in the sector unit, to reproduce the data in a simple fashion at a high speed, data to be recorded on the disk is divided into data in a predetermined unit so as to add a first error correction (C,) code to each of the resultant data, which form (C,) correction blocks. Sectors are produced each including a plurality of (C,) correction blocks. Added to each (C,) correction block is a code enabling identification of a sector. To all data in the plural (C,) correction blocks, a second error correction (C,) code is added to record the resultant data on the disk to allow interleaving or deinterleaving completing in a block. The capacity of each sector is set to be substantially equal to that of a plurality of transport packets.
