US 2025/0149062 A1 · SINGLE DATA BAND DATA STORAGE

Abstract

Provided are a computer program product, device, system, and method for single data band data storage. In one embodiment, a tape head module has an array of four servo transducer elements for each servo band of a tape and an array of reader/writer transducer elements extending over most of the width of the tape. In another embodiment, a data storage tape has a top servo band positioned adjacent a top edge guard band of the tape, a bottom servo band positioned adjacent a bottom edge guard band of the tape, and a single data band positioned between the top and bottom servo bands and configured to receive tracks of data written by a tape head wherein the single data band width extends over most of the tape width.

Dependent claims

A tape head for writing tracks of data on magnetic tape having a plurality of servo bands and a tape width WTape extending between longitudinal edges of the tape, comprising:

a module having a substrate, an array of NE transducer elements carried on the substrate and configured to one of 1) write to, and 2) read from a single band of data on the tape having a single data band width WDB wherein the NE transducer element array and the single data band width WDB each extend over most of the tape width WTape;
and
an array of four servo transducer elements carried on the substrate for each servo band of the tape for a total of eight servo transducer elements on the tape head module.

A method, comprising:

transferring data between a first tape head module and a single data band of a magnetic tape having a tape width WTape extending between longitudinal edges of the tape, wherein the transferring data includes one of writing to and reading from the single data band which extends over most of the tape width WTape, using an array of NE transducer elements of the first tape head module wherein the array of NE transducer elements extends over most of the tape width WTape, and further including controlling the lateral position of the first tape head module relative to the magnetic tape using an array of four servo transducer elements on the first tape head module for each servo band of the tape for a total of eight servo transducer elements on the first tape head module.

A data storage system for a magnetic tape having a plurality of servo bands and having a tape width WTape extending between longitudinal edges of the tape, comprising:

a first tape head module having an array of NE transducer elements and an array of four servo transducer elements for each servo band of the tape for a total of eight servo transducer elements on the first tape head module wherein the array of NE transducer elements extends over most of the tape width WTape;
a processor;
and
a computer readable storage medium, implemented in the data storage system, having computer readable program code embodied therein that when executed performs operations, the operations comprising:
transferring data between the first tape head module and a single data band of the tape, wherein the transferring data includes one of writing to and reading from the single data band;
and
controlling the lateral position of the first tape head module relative to the magnetic tape using the servo transducer elements on the first tape head module.
