Full title and description

Information technology - Digitally recorded media for information interchange and storage - 120 mm Triple Layer (100,0 Gbytes single sided disk and 200,0 Gbytes double sided disk) and Quadruple Layer (128,0 Gbytes single sided disk) BD Recordable disk. Specifies the mechanical, physical and optical characteristics, signal and recording quality, data format and error‑correction methods for 120 mm BD‑R media (write‑once, read‑many) to enable reliable interchange between disk drives and data processing systems.

Abstract

ISO/IEC 30191:2021 defines the physical, mechanical and optical parameters and test conditions for Triple‑Layer (TL) and Quadruple‑Layer (QL) 120 mm Blu‑ray recordable (BD‑R) disks with nominal capacities of 100.0 GB (single‑sided TL), 200.0 GB (double‑sided TL) and 128.0 GB (single‑sided QL). The standard covers track and sector layout, recorded/unrecorded signal quality, coding and error correction, conformance conditions, environmental and durability requirements, and reference measurement/drive conditions necessary to ensure media and drive interoperability for archival and interchange use.

Scope

This standard specifies three related types of 120 mm BD recordable disks (100.0 GB TL single‑sided, 200.0 GB TL double‑sided, and 128.0 GB QL single‑sided). It establishes the mechanical dimensions, optical stack and layer characteristics, track and sector formatting, recorded and unrecorded signal quality limits, channel coding and error correction methods, conformance test conditions and environmental/operational requirements so that disks and drives from different manufacturers can interchange data reliably. When combined with a volume/file structure standard (for example UDF), it supports full data interchange between data processing systems.

Key topics and requirements

• Mechanical and dimensional characteristics to ensure mechanical interchangeability (clamping zone, information area, rims).
• Optical and layer stack specifications for multi‑layer BD‑R media (thickness, refractive index, reflectivity, birefringence limits).
• Recorded and unrecorded signal quality requirements and read‑channel definitions for reliable playback/readback.
• Data format, frame/sector structure, addressing and logical data cluster coding for media interchange.
• Error detection and error‑correction coding strategy (ECC, interleaving, EDC) to provide read reliability.
• Recording method definition (write‑once, read‑many) and recommended reference drive/measurement conditions.
• Environmental, storage and durability requirements (temperature/humidity ranges, mechanical shock, scratch/fingerprint resistance).
• Conformance tests and acceptance criteria for manufacturers and test laboratories.

Typical use and users

Manufacturers of optical media and BD‑R discs, optical drive and firmware developers, test laboratories and quality assurance teams, data archivists and IT professionals selecting write‑once archival media, and procurement or compliance teams requiring standardized interchange and conformance criteria for BD recordable media.

Related standards

The ISO/IEC 3019x family and other optical‑media standards are closely related. Example related standards include ISO/IEC 30192 and ISO/IEC 30193 (other BD media types and rewritable formats), standards for volume and file structure (e.g., UDF specifications) and Blu‑ray Disc format/specifications used by industry fora. These documents are typically used together to ensure full data interchange and compatibility between media, drives and file systems.
