Abstract
PURPOSE:To enable to control a floppy disk device even without the receiving means of a positioning completion signal by prohibiting the transmission of a read data signal and an index signal until it is detected that the position error of a magnetic head against an objective track comes smaller than a prescribed value. CONSTITUTION:It is constituted of the magnetic head 11, a regeneration circuit 12, a magnetic head position detection circuit 13, a positioning completion signal output circuit 14, an index detector 15, an index pulse generation circuit 16 and a prohibition circuit 17. Then, until the positioning completion signal output circuit 14 detects that the position error of the magnetic head 11 against the objective track, detected by the magnetic head position detection circuit 13, comes smaller than a predetermined definite value, the transmission of the read data signal and the index signal to the floppy disk control device 2 is prohibited. Thus, even when the means to receive the positioning completion signal is not provided, the floppy disk device 1 can be controlled.
