Abstract
In one embodiment, a computer program product includes a computer readable storage medium having program instructions embodied therewith, the program instructions readable/executable by a controller to cause the controller to: determine and/or receive, by the controller, a selection of which of at least two track width formats to use during writing of data on a magnetic recording tape, wherein the track width format is selected based on an environmental condition; and cause, by the controller, simultaneous writing of a plurality of data tracks to the magnetic recording tape using only one of the track width formats at a same time such that each of the data tracks written at the same time has a track width that is substantially the same.
Claims19
A computer program product, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions readable/executable by a controller to cause the controller to:
- determine and/or receive, by the controller, a selection of which of at least two track width formats to use during writing of data on a magnetic recording tape, wherein the track width format is selected based on an environmental condition;
- and
- cause, by the controller, simultaneous writing of a plurality of data tracks to the magnetic recording tape using only one of the track width formats at a same time such that each of the data tracks written at the same time has a track width that is substantially the same.
A computer program product, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions readable/executable by a controller to cause the controller to:
- determine, by the controller, which of at least two track width formats was used during writing of data tracks on a magnetic medium recording tape;
- and
- cause, by the controller, reading of the data tracks from the magnetic recording tape using the determined track width format,
- wherein which of the at least two different track width formats used during writing of the data tracks on the magnetic recording tape is selectable based on an environmental condition,
- wherein all data tracks on the magnetic recording tape having the determined track width format have about a same track width.
A product, comprising:
- a magnetic recording tape having linear data tracks written thereon, each data track extending in a longitudinal direction along the magnetic recording tape,
- wherein a first set of the data tracks are written according to a first track width format,
- wherein a second set of data tracks are written according to a second track width format that is different than the first track width format;
- wherein the track width formats of the first and second data tracks are selected based on an environmental condition at the time of writing, wherein the environmental condition includes at least one of a vibrational environmental condition and a tape dimensional stability (TDS) environmental condition;
- and
- at least one reel configured to support the magnetic recording tape.
