Data recording apparatus able to accurately access a floppy disk regardless of recording density

摘要: A floppy disk drive apparatus capable of using high- and low-density disks includes an erase section. When it is determined that a to be used has high-density, data immediately written on the in response write command. However, when low-density, data, which previously been recorded recording area track where read/write head currently located, erased prior writing new data. After erasure completed, area, signal.
