ABSTRACT:
A method of adjusting the lateral position of writing on a magnetic tape. A magnetic tape recording is provided having a first track including alternate data and servo information wherein the data is written at a first azimuth angle and the servo information is written at a second azimuth angle, and having a second track including alternate data and servo information wherein the data is written at the second azimuth angle and the servo is written at the first azimuth angle. The first track is monitored during writing of the second track for the presence of servo blocks. Writing in the second track is interrupted upon the sensing of alternate servo blocks in the first track. Amplitudes of servo blocks received during writing are compared with amplitudes of alternate servo blocks received while writing is interrupted, and the lateral position of writing is adjusted in response.
