Abstract

PURPOSE:To realize an immediate decision for the quality of an information track, by providing a table storing the quality of the track in accordance with the address of the track. CONSTITUTION:A track address signal 11, i.e., an output signal given from a host processor is stored temporarily in a register 1 by a track register load signal 15. Thus the contents (information on the quality of the corresponding track) of a memory address corresponding to the address signal 11 in a PROM2 is read out. If the corresponding track is nondefective, the track address is delivered in the form of an effective track address 20. While a bad track display signal 13 is delivered from the PROM2 to be transferred to the host processor if the corresponding track is defective.
