Bar Code Reader
Using the bar code reader, the tape library can identify tape cartridges by bar code labels that you can slide into the face of the cartridge.
If a label is missing, the tape can be identified by its recorded data.
The tape library bar code reader consists of a light-emitting diode (LED) light bar and a charge-coupled device (CCD) optical sensor located next to the removable magazine.
The tape library reads a bar code by moving a tape cartridge from a cell and positioning the cartridge in front of the bar code reader.
With the bar code reader, a complete cartridge inventory can be performed in approximately five minutes.
