ABSTRACT:
A recording/reproducing device for use in a floppy disk apparatus. The device has a first coil and a second coil, both wound arond a common core. The coils are connected to each other at one end, and have taps, respectively. Both coils have characteristics optimized for data-reading. A read circuit is connected to the second ends of the coils. A write circuit is connected to the taps of the coils. The write circuit writes data on a recording medium by using that portion of the first coil which extends between the tap of the first coil and the connection point between the coils, and that portion of the second coil which extends between the tap of the second coil and the connection point between the coils.
