SYSTEM FOR RECORDING AND/OR REPRODUCING INFORMATION, MEDIUM FOR USE IN THE SYSTEM, AND MAGNETIC EMBOSS HEAD AND ARRANGEMENT FOR FORMATTING THE MEDIUM

摘要

The invention relates to a magnetic tape (10) formatted by means of a magnetic emboss head (60), and an apparatus comprising a magnetic data head (20) which is movable in a transverse direction (y) by means of an actuator (40). By means of the magnetic emboss head (60) the magnetic tape (10) has been provided with a pattern of servotracks ST1-ST17 which extend in a longitudinal direction (x). The odd-numbered servotracks contain a first servosignal and the even-numbered servotracks contain a second servosignal which is in phase opposition to the first servosignal. The servotracks ST2-ST8 and ST10-ST16 have a typical width W1 and form a group of two bands of seven servotracks which are separated by a band having a typical width D=(k+1/2)W1, where k=0, 1, 2 etc. The pattern of servotracks is suited to position a magnetic data head (20) of a first generation at four different positions and suited to position a magnetic data head (120) of a second generation at eight different positions by controlling the actuator in response to the servosignal (V1-V4) read by the data channels.
