[. . . ] This specification contains the following information about the bar code labels: !Label Orientation on Cartridge Symbology The LTO Ultrium cartridge label uses the bar code symbology of USS-39. A description and definition of this symbology is available from the Automatic Identification Manufacturers (AIM) specification Uniform Symbol Specification (USS-39) and the ANSI MH10. 8M-1993 ANSI Barcode specification. Bar Code Characters The bar code string consists of a start character, eight alphanumeric characters, and the stop character. The first six characters may be any combination of upper case A through Z or 0 through 9 (for example, ABC123) to identify the cartridge volume. The last two characters are determined by the LTO Ultrium cartridge media type (for example "L" for LTO Ultrium and "1" for tape cartridge generation or drive manufacturer-unique identifier). Only upper case alpha A through Z or numeric 0 through 9 characters are allowed. Human readable characters may be used, provided there is not a conflict or interference with the automation code. The user specifies the format, colors, and location of the human readable characters. Encodation Refer to the AIM Uniform Symbol USS-39 specification for the description and format of the start character, identifier characters, and stop character. Quiet Zone The quiet zones are the areas preceding the start and after the stop characters. They are clear of any printing or reflective properties that could cause spurious reflections. The quiet zones are further defined in the AIM Uniform Symbol USS-39 specification. 5 LTO Autoloader Barcode Reader Optical Specification The optical specifications for the bar code labels are listed below. Use the white calibration standard to calibrate the print contrast of the Mcbeth PCMII. Be sure the filter select switch is on position A for all calibration and measurements. The reflectivity of the white background (RW) is the reflectivity measured in the center of narrow spaces using the Mcbeth PCMII print contrast meter. At this measurement, isolated print defects and edge roughness are avoided. A spot is defined as an area anywhere within the white background in which the reflectivity is less than 65%. Spots may not be greater than 0. 004 inches (0. 102 mm) enclosed diameter. Spots may not be any closer to each other than 0. 01 inches (0. 254 mm). The reflectivity of the black areas (RB) may be measured anywhere within any black area on the bar code. The print contrast signal (PCS) is defined as (RW-RB)/RW and is measured using the Mcbeth PCMII print contrast meter. Using the PCS measurement will avoid isolated print defects and edge roughness. [. . . ] When the drive requires cleaning, it will request loading of the unique type cleaner cartridge. Diagnostic/Service cartridges use the prefix "DG{ space} vnnL1". The "v" field is an alphanumeric field to identify a drive-unique diagnostic cartridge, if required. The "nn" alphanumeric field identifies a specific diagnostic cartridge volume. [. . . ]
