<p>PROBLEM TO BE SOLVED: To provide a magnetic recording/reproducing device capable of reducing track thinning by a simple structure. SOLUTION: Pilot signals f1 and f2 are read by a drum 7 and ATF error dataΔE is produced by an ATF detection circuit 1. A system controller 4 calculates a parameter to be added to the ATF error dataΔE during consecutive recording of heads by an automatic measuring circuit 2 if there is no parameter stored in a storing part 3. During the consecutive recording, an adding circuit 9 and a capstan driving circuit 6 are connected by a change-over switch 5.</p> |
