Sony patents magnetic tape servo system for angled data heads
Sony has secured a patent for a device that writes specific alignment patterns onto magnetic tape. The system uses a specialized head to create asymmetric patterns that help data heads, which are physically tilted, write information accurately.
In the filing’s own words
A servo recording apparatus according to the present technology includes: a servo write head. The servo write head writes a first servo pattern and a second servo pattern to a plurality of servo bands of a magnetic tape, the first servo pattern and the second servo pattern being asymmetric with respect to a width direction of the magnetic tape, the magnetic tape being used in a data recording apparatus that includes a data write head disposed such that a longitudinal direction of the data write head is inclined with respect to the width direction of the magnetic tape by a first head azimuth angle.
What exactly they claim (claim 1)
1. A servo recording apparatus, comprising: a servo write head that writes a first servo pattern and a second servo pattern to a plurality of servo bands of a magnetic tape, the first servo pattern and the second servo pattern being asymmetric with respect to a width direction of the magnetic tape, the magnetic tape being used in a data recording apparatus that includes a data write head disposed such that a longitudinal direction of the data write head is inclined with respect to the width direction of the magnetic tape by a first head azimuth angle, wherein the servo write bead includes a plurality of pairs of servo elements corresponding to the plurality of servo bands, each of the pairs of servo elements including a first servo element that writes the first servo pattern and a second servo element that writes the second servo pattern.
