Recording and reproducing device and recording and reproducing method

A recording and reproducing method of a magnetic tape including a plurality of servo bands, on which servo patterns are recorded, and data bands which are provided between the servo bands and on which data is recorded, the method comprising:

• acquiring servo band interval information representing an interval, in a width direction of the magnetic tape, between adjacent servo recording elements of a plurality of servo recording elements which record the servo patterns on the plurality of servo bands, respectively;
• acquiring reproducing element interval information representing an interval in the width direction between respective servo reproducing elements which read the adjacent servo patterns along the width direction with respect to the plurality of tape drives;
• and
• selecting, from a plurality of tape drives of a recording and reproducing device, a tape drive into which the magnetic tape is inserted, using a value representing a difference between the interval represented by the servo band interval information and the interval represented by the reproducing element interval information.

A non-transitory storage medium storing a program that causes a computer to execute a recording and reproducing processing of a magnetic tape including a plurality of servo bands, on which servo patterns are recorded, and data bands which are provided between the servo bands and on which data is recorded, the recording and reproducing processing comprising:

• acquiring servo band interval information representing an interval, in a width direction of the magnetic tape, between adjacent servo recording elements of a plurality of servo recording elements which record the servo patterns on the plurality of servo bands, respectively;
• acquiring reproducing element interval information representing an interval in the width direction between respective servo reproducing elements which read the adjacent servo patterns along the width direction with respect to the plurality of tape drives;
• and
• selecting, from a plurality of tape drives of a recording and reproducing device, a tape drive into which the magnetic tape is inserted, using a value representing a difference between the interval represented by the servo band interval information and the interval represented by the reproducing element interval information.
