A magnetic recording/reproduction apparatus includes a first floppy disk drive (FDD) of a preerase head type, which includes a first read/write (R/W) section, and a second FDD of a tunnel erase head type, which includes a second R/W section. A selection signal generating section selectively outputs first and second selection signals generated in accordance with a write command for said first and second FDD. A mode signal supplying section outputs a mode signal generated in accordance with the write command to a write gate (WG) signal generating section. A sync signal generating section generates a sync signal from a read data (RD) signal from the first or second R/W section and sends it to the R/W signal generating section. In response to the sync signal, the WG signal generating section generates a first WG signal for the first FDD and a second WG signal for the second FDD and selectively outputs one of the first and second WG signals to the first and second FDDs in accordance with the mode signal received from the mode signal supplying section. In accordance with the received WG signal and the first and second selection signals, the first and second FDDs record data corresponding to an incoming write data (WD) signal on a disk, read out the recorded data from the disk and generate first and second RD signals corresponding to the read recorded data as the RD signal.
