SIGNAL RECORDING/REPRODUCTION APPARATUS AND METHOD OF CHANGING ERROR RECOVERY PROCESS EXECUTION SEQUENCE

摘要

This invention relates to an efficient execution of error recovery process of a signal read error in a signal recording/reproduction apparatus. The apparatus has a table for defining an execution sequence of a plurality of error recovery processes, and one structural body is allocated to each error recovery process in this table. Each structure has an address for calling a corresponding error process and addresses of corresponding error recovery processes to be executed precedingly and subsequently. The addresses relating to the preceding and subsequent structures are re-written by a LRU method of a weighing method so as to change the chain relation of the structures, and an optimum error process can be executed more quickly.
