ANSI INCITS 329-2000 pdf download Magnetic Tape Cartridge for Information Interchange 0.50 in (12.65 mm), Serial Serpentine, 208-Track, 85 938 bpi (3383 bpmm) DLT5 Format
1. Introduction
1.1 Scope
This standard provides the requirements for a tape cartridge to be used for information interchange among information-processing systems, communication systems, and associated equipment utilizing a standard code for information interchange as agreed upon by the interchange parties. This standard deals with the requirements for the unrecorded cartridge and for recording on the enclosed magnetic tape.
The use of a labeling standard such as American National Standard for Information systems – File structure and labeling of magnetic tapes for information interchange, X3.27-1987 or later editions, 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 nondiscriminatory 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 information 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 levels of performance for interchange purposes. They, therefore, represent the performance levels that the interchange items should meet or surpass during their useful life and thus define end-of-life 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.
