Patent ID: 7889454

Claim:
A magnetic tape medium comprising: a plurality of data bands that extend along a length of the magnetic tape medium, wherein the plurality of data bands are distributed across a width of the magnetic tape medium and wherein each of the data bands includes a plurality of data tracks; and a plurality of servo bands that extend along the length of the magnetic tape medium, wherein the plurality of servo bands are distributed across the width of the magnetic tape medium and wherein each of the servo bands separates two of the data bands, wherein each of the servo bands defines an amplitude-based servo pattern that defines a centerline and windows above and below the centerline, wherein each of the servo bands defines a servo band width that corresponds to a width of two of the data tracks within the data bands, wherein each of the servo bands provides positioning information, and a respective one of the servo bands provides positioning information for at least one of the data bands that is adjacent to the respective one of the servo bands, wherein distances between the servo bands across the width of the magnetic tape medium are less than 200 micrometers, and wherein widths of each of the servo bands across the width of the magnetic tape medium are less than 20 micrometers.
