ANSI-INCITS-334:2000 pdf download.Information Technology一Magnetic Tape Cartridge for Information Interchange 0.50 in (12.65 mm), Serial Serpentine l28-Track, 62 500 bpi (2 460 bpmm) DLT 3-XT Format.
ANSI-INCITS-334 specifies the physical and magnetic characteristics of a 0.5 in (12.65 mm) wide 128-track magnetic tape cartridge, to enable physical interchange of such cartridges. It also specifies the quality of the recorded signals, a format – called Digital Linear Tape 3 Extended (DLT 3-XT) – and a recording method, thereby allowing data interchange between drives.
The use of a labeling standard such as American National Standard for Information Technology – File structure and labelling of magiietic tapes ftr infrrmtaio,z infrrchange, ANSI X3.27- 1987(R 1995), will support data interchange between data-processing systems.
Note – The user’s attention is called to the possibility that compliance with this standard may require use of an invention covered by patent rights.
By publication of this standard, no position is taken with respect to the validity of this claim or of any patent rights in connection therewith. The patent holder has, however, filed a statement of willingness to grant a license under these rights on reasonable and non-discriminatory terms and conditions to applicants desiring to obtain such a license. Details may be obtained from the publisher.
1.2 Purpose
This standard defines the requirements and supporting test methods necessary to ensure intormation interchange at acceptable performance levels. It is distinct from a specification in that it delineates a minimum of restrictions consistent with compatibility in interchange transactions.
The performance level contained in this standard represents the minimum acceptable level of performance for interchange purposes. They, therefore, represent the performance levels that interchange items should meet or surpass during their useful life and thus define end-of-line criteria for interchange purposes. The performance levels in this standard are not intended to be employed as substitutes for purchase specifications.
Wherever feasible, quantitative performance levels that shall be met or exceeded to comply with this standard are given. In all cases, including those in which quantitative limits for requirements falling within the scope of this standard are not stated but left to agreement between the interchange parties. standard test methods and measurement procedures shall be used to determine such limits.
The interchange parties complying with the applicable standards should be able to achieve compatibility without the need for additional exchange of technical information.
1.3 Conformance
1.3.1 Magnetic tape cartridges
A magnetic tape cartridge shall be in conformance with this standard if it satisfies all mandatory requirements of this standard. The tape requirements shall be satisfied throughout the extent of the tape.ANSI-INCITS-334 pdf download.
