When the setting of an automatic head switching mode is received from the outside, an automatic head switching control unit automatically switches the contents of the head address control register and sequentially outputs the head selection signals to a plurality of heads synchronously with a write gate signal (WRGT signal) E,to instruct the writing operation from the outside.
