Abstract
A tape drive may arrange timing-based-servo marks into a timing-based-servo pattern. The timing-based-servo pattern may be at least one M-pattern. The tape drive may select the at least one M-pattern. The tape drive may match at least two timing-based-servo marks in the at least one M-pattern. The tape drive may determine, from the matching, whether an alignment of the at least two timing-based-servo marks is demonstrative of tape-creep.
Claims16
A method for allowing a tape drive to read from a tape cartridge with timing-based-servo marks, wherein the tape cartridge is a dual-reel tape cassette that stores a tape-media, the method comprising:
- arranging the timing-based-servo marks into a timing-based-servo pattern, wherein the timing-based-servo pattern is at least one M-pattern;
- selecting the at least one M-pattern;
- matching at least two timing-based-servo marks in the at least one M-pattern;
- and
- determining, from the matching, whether an alignment of the at least two timing-based-servo marks is demonstrative of tape-creep, wherein the tape-creep is determined for the tape-media stored in the dual-reel tape cassette.
A system comprising:
- a tape drive;
- and
- a tape cartridge with timing-based-servo marks, wherein the tape cartridge is a duel-reel tape cassette that stores a tape-media, wherein the tape drive reads from the tape cartridge, and wherein the tape drive is configured to perform the operations comprising:
- arranging the timing-based-servo marks into a timing-based-servo pattern, wherein the timing-based-servo pattern is at least one M-pattern;
- selecting the at least one M-pattern;
- matching at least two timing-based-servo marks in the at least one M-pattern;
- and
- determining, from the matching, whether an alignment of the at least two timing-based-servo marks is demonstrative of tape-creep, and wherein the tape-creep is determined for the tape-media stored in the dual-reel tape cassette.
