Tape label
Tape labels are identifiers given to volumes of magnetic tape.
There are two kinds of tape labels. The first is a label applied to the exterior of tape cartridge or reel. The second is data recorded on the tape itself.
Visual labels
Visual labels are human readable.
The labels have evolved to have barcodes that can be read by tape libraries. Reading the barcode label is often much faster than mounting the tape volume and reading the identification information written on the media. To read the bar code, the tape library need only position the volume in front of the bar code reader.
Magnetic labels
Originally, 7- and 9-track
A solution was to record some tape identification information on the tape itself in a standard format. This
Some computer systems used similar labels on other serial media, for example punched card decks and sometimes line printer output.
IBM tape labels
IBM tape labels with VOL/HDR/EOV/EOF records.[1] IBM tape labels on 9-track tapes use EBCDIC character encoding; 7-track tapes (now obsolete) used BCD encoding.[2]
ANSI tape labels
ANSI/ISO/ECMA tape labels are similar to IBM tape labels but use the ASCII character set on 9-track tape. When originally defined in the mid-1960s, they used BCD on 7-track tape.
