ABSTRACT:
In a rotary head height measuring system 50, a peak position detector 51 detects peak positions of output signals of rotary heads 62-65 mounted on a magnetic recording and reproduction system 60. A time difference detector 52 detects a time difference .DELTA.t between specific peaks based on the peak positions detected by the peak position detector means 51. An altitudinal dislocation calculating means 53 calculates an altitudinal dislocation .DELTA.h of a concerned rotary head based on the time difference .DELTA.t obtained by the time difference detector 52. During the measurement of rotary head height, a tape in the magnetic recording and reproduction system 60 is driven at a specific travelling speed which is k times a regular reproduction speed of magnetic recording and reproduction system, where k is not larger than -1 or not smaller than 2.
