Specifies the conditions for conformance testing and the reference drive, the environments in which the cartridges are to be operated and stored, the mechanical, physical and dimensional characteristics of the cartridge, the format of the information on the disk, the magneto-optical characteristics of the disk and the minimum quality of user-written data on the disk.

Overview

ISO/IEC 13842:1995 - "Information technology - 130 mm optical disk cartridges for information interchange - Capacity: 2 Gbytes per cartridge" defines a complete interchange specification for 130 mm optical disk cartridges (ODCs) with a nominal capacity of 2 Gbytes per cartridge (two sides, nominally 1 Gbyte per side). The Standard specifies mechanical, physical and optical characteristics, the on-disk format (tracks, sectors, ECC and modulation), magneto‑optical recording requirements, environmental and safety conditions, and the conformance testing framework including a defined Reference Drive.

Key topics and technical requirements

Physical & mechanical characteristics: Detailed case and disk dimensions, hub and clamping zones, shutter and sensor openings to ensure mechanical interchangeability between drives.

Environments & tests: Test, operating, storage and transportation conditions plus temperature‑shock and drop tests.

Reference Drive & conformance: Definition of a Reference Drive (optics, tracking, read channels, rotation) and conditions for claiming conformance by cartridges, generating systems and receiving systems.

Format of information: Track geometry (physical and logical tracks), sector layouts (512‑byte and 1 024‑byte sector sizes supported), control tracks, lead‑in/lead‑out, and formatted zones (user, manufacturer, embossed).

Recording & magneto‑optical characteristics: Write/erase conditions, write pulse definitions, Kerr rotation, modulation methods, figure of merit and signal/noise and jitter requirements for reliable read/write.

Defect management: Primary and Secondary Defect Lists (PDL/SDL), initialization, certification and slip/linear replacement algorithms for both rewritable and write‑once areas.

Quality requirements: Minimum quality metrics for embossed and user‑written data, error correction (Reed‑Solomon, CRC), interleaving and timing/jitter measurement methods.

Annexes & test methods: Extensive normative and informative annexes covering measurement procedures (jitter, C/N, figure of merit), environment derivation, sector retirement, and implementation‑independent mark quality.

Applications and practical value

Enables reliable data interchange between optical disk drives across manufacturers.

Used for archival storage, backups, and long‑term offline media interchange where mechanical and format compatibility is critical.

Supports mixed media types (rewritable, write‑once, pre‑recorded/embossed) for distribution, duplication and archival workflows.

Provides test and conformance procedures for product qualification, QA labs and procurement specifications.

Who should use this standard

Optical disk and cartridge manufacturers (media, drive vendors)

Systems integrators and data center/archival managers specifying interchange media

Conformance testers, certification labs and standards bodies

Software/hardware developers implementing low‑level drive interfaces and file/volume interchange layers

Related standards

Normative reference: IEC 950 (Safety of information technology equipment) is cited for electrical and safety requirements.
