摘要： A combined magnetic head system for recording a data track on a guard band between main tracks of a floppy disk. The system includes a control device for controlling a transfer mechanism so that the level of a second signal becomes equal to that of a third signal during the recording of a first signal, or so that the level of a first signal is maximized during the reproduction thereof, or so that a level of one of the reproduced second or third signals is maximized during the recording of the first signal. A guard band data head for data tracks is positioned above the guard band and has width so as to record satisfactorily data on the guard band without degrading recorded information on the main tracks irrespective of whether the recording is performed with the data head stretching over the main tracks. The width is preferably between 40% and 60% of the guard band.
