System for recording and/or reproducing information medium for use in the system and magnetic head for formatting the medium

摘要

The invention relates to a system for recording and/or reproducing information, comprising a magnetic tape and an apparatus comprising a magnetic head unit which is movable on a transverse direction by means of an actuator. By means of a write head, the magnetic tape has been provided with a pattern of servotracks ST101-ST127 which extend in a longitudinal direction. The odd-numbered servotracks contain a first servosignal and the even-numbered servotracks contain a second servosignal which is phase opposition to the first servosignal. The servotracks ST103-ST113 and ST116-ST126 have a typical width W1 and form a group of two bands of N1 servotracks which are separated by a band of N2 servotracks ST114, ST115 having a typical width W2. The magnetic tape is adapted to cooperate with an apparatus comprising eight magnetic heads. The actuator is controlled in response to the servosignals read by the heads.
