Abstract

A magnetic tape of the present invention includes a plurality of data bands in which a data signal can be recorded and servo pattern portions composed of a burst signal. The servo pattern portions are formed at a predetermined interval in a longitudinal direction of the magnetic tape in a plurality of data bands, and positions of the servo pattern portions formed in the respective data bands in the longitudinal direction of the magnetic tape vary. According to such a configuration, a magnetic tape can be provided, which is traced stably by the magnetic head even if the magnetic tape is deformed due to temperature and humidity.

Claims (17)

1. A magnetic tape, comprising:

a data band in which a data signal is capable of being recorded; and

a servo band in which a plurality of servo tracks including servo patterns for performing a servo control are formed,

wherein the servo band is formed so that the servo patterns are composed of a burst signal and are placed continuously in a longitudinal direction of the magnetic tape, and

assuming that the number of a plurality of data tracks is N per data band, the number of the plurality of servo tracks is N+1.

2. A magnetic tape, comprising:

a plurality of data bands in which a data signal is capable of being recorded; and

servo patterns composed of a burst signal,

wherein the servo patterns are formed at a predetermined interval in a longitudinal direction of the magnetic tape in the plurality of data bands, and

positions of the servo patterns in the longitudinal direction of the magnetic tape vary depending upon the data band, and

the servo patterns are formed so as not to be adjacent to each other between the respective data bands.

3. A magnetic tape, comprising:

a plurality of data bands in which a data signal is capable of being recorded; and

stripe-shaped servo patterns formed so as to be tilted in a longitudinal direction of the magnetic tape,

wherein the servo patterns are formed at a predetermined interval in the longitudinal direction of the magnetic tape in the plurality of data bands,

positions of the servo patterns in the longitudinal direction of the magnetic tape vary depending upon the data band, and

the servo patterns are formed so as not to be adjacent to each other between the respective data bands.
