Abstract

PURPOSE: To record and reproduce information with ability to correct a host of errors by recording the information on an information recording medium on a block basis and further recording information regarding the type of the ability of said information.

For recording, original data of one track is converted into data with ECC in accordance with the type of ECC, and the data is recorded on the data track 10 of an optical card. After the data is recorded on the final track of a file, data converted into the directory part 20 of the optical card is recorded. For reproducing, data with ECC is converted into original data. Data on an object track is read in, and it is judged to be data with ECC. In accordance with the type of ECC, data with ECC is converted into original data.
