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.

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 an 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;
media capacity of the at least one of the units of removable data storage media; and,
an age of the at least one of the units of removable data storage media.
8. The computer-readable medium of claim 5 wherein the received identifier comprises a bar code or radio frequency identification tag.
9. The computer-readable medium of claim 5 , further comprising:
determining that the number of media identifiers included in the subset satisfies a threshold, and wherein the threshold is user defined or is pre-set.
10. The computer-readable medium of claim 5 wherein the process is for automatically identifying identifiers associated with multiple units of removable data storage media in an automated data storage library, wherein the automated data storage library can not read at least one identifier for at least one of the units of removable data storage media because of a portion of a type or length of the identifier, because a portion of the identifier is not scanned, or because a portion of the identifier is damaged, misaligned or is otherwise unreadable.
11. A method, comprising:
