ABSTRACT:
When video signals, audio signals, computer data, etc. are recorded in digital fashion on a magnetic tape, the timing at which the control pulse is recorded is set appropriately. The control pulse forming circuit (31) sets a travel distance of the magnetic tape (4) from a position midway of the digital signal pattern (D.sub.2) now being recorded by the 2ch second magnetic head (8b) to the outlet position of the digital signal pattern (D.sub.2) to a .DELTA.X value, when the 2ch first magnetic head (7b) reaches the outlet position of a virtual video signal pattern (V.sub.2), without recording with advance of magnetic tape travel; and further records the control pulse C by shifting the recording timing of the control pulse C by a value corresponding to the .DELTA.X value relative to a prescribed distance X value on the magnetic tape (4).
