System and method for improved media identification in a storage device
View Patent ↗Systems and methods are provided for improved identification of removable storage media. A scanner may be used to read an identifier, such as a barcode, on a removable storage media. In the event that the scanner reads the identifier incorrectly due to a defect in the barcode, such as a damaged label, misaligned identifier, or because the scanner is incapable of reading the identifier type or the scanner's field of view is incorrect, a media management component receives the scanned identifier data and matches it to a known set of media identifiers to create a subset of matching identifier data. A closest matching media identifier may be identified from the subset of matching identifier data. An index may be updated with information indicating the closest matching media identifier and a location of the removable storage media.

determining that received data for an identifier of a unit of removable data storage media is new or is not recognized;
matching the received data to a set of known media identifiers, wherein the matching includes at least one of pattern matching, order matching, length matching, character type matching, or sum matching;
identifying a subset of known media identifiers among the set of known media identifiers that match the received identifier; and,
identifying at least one closest match among the subset of known media identifiers to the received identifier.
6. The computer readable medium of claim 5 wherein the pattern matching includes matching at least a ratio of 6 of 8 characters,
wherein the order matching includes matching at least a ratio of 4 of 6 characters in a same consecutive order,
wherein the length matching includes matching a length of the identifier to a length of stored media identifier data,
wherein the character type matching includes determining whether certain positions of the identifier correspond to alphanumeric characters appearing in the same positions in stored media identifier data, and
wherein a sum of the characters of the identifier equals a sum of characters comprising a stored media identifier.
7. The computer readable medium of claim 5 further comprising receiving data indicating a location of the removable storage media; and
updating an index entry with the closest match among the subset of known media identifiers with the data indicating the location of the removable storage media, wherein the index includes at least three of:
a slot location in the automated data storage library;
a media type for the at least one of the units of removable data storage media;
information relating to data on the at least one of the units of removable data storage media;
