Information processing with tape
- File structure and labeling
1 Scope
This standard specifies the user among the information processing system of information exchange tape text structure and labeling.
This standard also specifies.
--- Volume and file structure;
--- Block basic characteristics (these blocks contain records constituting the file);
--- Identification tape files, and record label segment volume;
--- Four nested levels of interchange.
In addition, the standard specifies the requirements for an information processing system provided the following purposes process. allowing information to use in magnetic recording
As with the exchange between different systems to exchange media. To this end, for those who intend to systems built or received in line with this standard tape volume, this standard
Quasi provides these systems to offer.
2 Conformance
2.1 Consistency tape volume set
When all of the information recorded on the tape volume set in line with the provisions of this standard, the tape volume set comply with this standard. Conformance Statement shall be identified magnetic
In line with the content of the minimum level of exchange.
Such consistency condition that the volume of each volume are in line with a set of standards for information exchange tape.
2.2 Consistency of Information Processing System
The information processing system, whether the system is built, the receiving system, or a combination of both systems, if they meet all the requirements of this standard to
Requirements, the information processing system meets this standard. Declaration of conformity shall identify the system can meet the requirements of these collections.
