Full title and description

Information technology — Data interchange on 356 mm optical disk cartridges — WORM, using phase change technology — Capacity: 14,8 Gbytes and 25 Gbytes per cartridge. The standard specifies physical, optical and logical characteristics for write-once, read-many (WORM) 356 mm optical cartridge media and associated data interchange requirements for generating and receiving systems.

Abstract

This standard defines the format and interchange requirements for 356 mm optical disk cartridges that use phase-change WORM recording at capacities of 14.8 GBytes and 25 GBytes per cartridge. It covers media physical dimensions and tolerances, recording and readback characteristics, logical data format and conformance criteria to enable interoperability between cartridge manufacturers and host systems.

Scope

Specifies the data interchange requirements for 356 mm optical disk cartridges employing phase-change WORM technology at the specified capacities. The scope includes physical cartridge and disk dimensions, optical and material properties relevant to recording and readback, permitted recording practices, logical data structures and conformance statements for generating and receiving systems to ensure compatibility between devices and media. It does not cover rewritable media formats or archival media beyond the defined cartridge dimensions and capacities.

Key topics and requirements

• Physical and mechanical characteristics of 356 mm optical cartridges (dimensions, tolerances, casing features).
• Optical and recording technology details for phase-change WORM media (write power, baseline reflectance, permissible recording zones).
• Defined capacities and data organization for 14.8 GByte and 25 GByte cartridges (logical format and file structures).
• Conformance and interoperability requirements for generating systems and receiving systems (compatibility statements and testable requirements).
• Cross-references and equivalence to related industry specifications (historically aligned with ECMA 260 and adopted identically by relevant national bodies).

Typical use and users

Used historically by optical media manufacturers, recorder and drive designers, system integrators and organizations operating WORM optical libraries for data interchange and archival distribution. Typical users included manufacturers implementing cartridge mechanical and optical specifications, test laboratories performing conformance testing, and IT archivists needing media interoperability. As the standard has been withdrawn, historical users rely on it for legacy-system support and documentation.

Related standards

Historically related or equivalent documents include ECMA-260 (corresponding specification), INCITS adoptions of the ISO/IEC text, and other ISO/IEC JTC 1/SC 23 outputs addressing digitally recorded media formats; later work on optical media quality and archival formats (for example, newer ISO/IEC publications on digitally recorded media) may be relevant for current practice.

FAQ

Q: What is this standard?

A: ISO/IEC 15898:1998 is an international standard that specified data interchange requirements for 356 mm optical disk cartridges using phase-change WORM technology, at capacities of 14.8 GBytes and 25 GBytes per cartridge.

Q: What does it cover?

A: It covered the physical, optical and logical characteristics necessary for interoperable data interchange between generating and receiving systems using the specified cartridges — including mechanical dimensions, optical recording/readback parameters and logical data organization.

Q: Who typically uses it?

A: Manufacturers of optical cartridges and drives, test laboratories, system integrators, and organizations maintaining legacy optical libraries or implementing archival WORM solutions were the primary users. Today it is mainly referenced for legacy support and historical compliance.

Q: Is it current or superseded?

A: ISO/IEC 15898:1998 has been withdrawn (withdrawal recorded by standards publishers). Implementers should consult current ISO/IEC or national body publications and newer industry specifications for up-to-date media formats and archival guidelines.

Q: Is it part of a series?

A: It was produced under ISO/IEC JTC 1/SC 23 (Digitally recorded media for information interchange and storage) and has equivalence relations with industry documents such as ECMA-260 and INCITS adoptions. It is one of several ISO/IEC standards addressing digitally recorded media.

Q: What are the key keywords?

A: Key terms include 356 mm optical cartridge, WORM, phase change, data interchange, cartridge format, and ISO/IEC JTC 1/SC 23.
