Abstract
Embodiments of the present invention provide a system, method, and computer program product for offsetting a reading head on a magnetic tape to improve verification. A processor determines a write head width, a read head width, and a track pitch based on determining an LTO standard of the magnetic tape. The processor determines a distance of the reading head from a writing head using the write head width, the read head width, and the track pitch, and causes a tape appliance to relocate the read head on the magnetic tape to the determined distance.
Claims20
A method for offsetting a read head on a magnetic tape to improve verification, the method comprising:
- determining a write head width, a read head width, and a track pitch based on determining an LTO standard of the magnetic tape;
- determining a distance of the read head from a write head using the write head width, the read head width, and the track pitch;
- and
- causing a tape appliance to relocate the read head on the magnetic tape to the determined distance, such that the read head does not extend beyond the track pitch.
A computer system for offsetting a read head on a magnetic tape to improve verification, the computer system comprising:
- one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
- determining a write head width, a read head width, and a track pitch based on determining an LTO standard of the magnetic tape;
- determining a distance of the read head from a write head using the write head width, the read head width, and the track pitch;
- and
- causing a tape appliance to relocate the read head on the magnetic tape to the determined distance, such that the read head does not extend beyond the track pitch.
A computer program product for offsetting a read head on a magnetic tape to improve verification, the computer program product comprising:
- one or more computer-readable tangible storage medium and program instructions stored on at least one of the one or more tangible storage medium, the program instructions executable by a processor, the program instructions comprising:
- program instructions to determine a write head width, a read head width, and a track pitch based on determining an LTO standard of the magnetic tape;
- program instructions to determine a distance of the read head from a writing write head using the write head width, the read head width, and the track pitch;
- and
- program instructions to cause a tape appliance to relocate the read head on the magnetic tape to the determined distance, such that the read head does not extend beyond the track pitch.
