ISO IEC 30190-2021 PDF

Full title and description

Information technology — Digitally recorded media for information interchange and storage — 120 mm Single Layer (25,0 Gbytes per disk) and Dual Layer (50,0 Gbytes per disk) BD Recordable disk. This international standard specifies the mechanical, physical and optical characteristics, signal and recording quality, data format, error-correcting codes and recording method for 120 mm BD recordable (BD‑R) discs so they can be interchanged and read across compliant drives and systems.

Abstract

ISO/IEC 30190:2021 defines the physical, mechanical and optical requirements and the logical data format for 120 mm BD‑R (Blu‑ray recordable) media in single‑layer (25.0 GB) and dual‑layer (50.0 GB) variants. It covers types of BD‑R disks, conformance conditions, operating and storage environments, track and sector layout, coding and error correction, and signal characteristics to enable reliable write‑once/read‑many interchange between drives and systems.

Scope

This document specifies three related types of 120 mm BD recordable discs (single layer and dual layer variants), the conditions for conformance, required operating and storage environments, mechanical and physical dimensions for interchange, the physical disposition of tracks and sectors, the coding and error‑correcting schemes used, and the recorded signal characteristics so that compliant drives and systems can reliably read recorded data. It is intended to provide full data interchange when used with appropriate file/volume structure standards.

Key topics and requirements

• Mechanical and physical dimensions and tolerances for 120 mm BD‑R discs (single and dual layer).
• Optical and signal characteristics required for reliable reading of recorded marks.
• Data formatting: track layout, sector structure and logical format elements required for interchange.
• Coding and error‑correcting schemes (including the ECC structure and coding methods).
• Conditions and methods for conformance testing and environmental storage/operating conditions.
• Definition of disc types and identification to ensure cross‑vendor compatibility.

Typical use and users

Manufacturers of BD‑R discs and optical disc drives, firmware and drive testing laboratories, data archivists and preservation specialists, system integrators and hardware designers who require precise interchange specifications for write‑once optical media. Also used by testing and certification bodies and by organizations implementing long‑term optical archival processes.

Related standards

ISO/IEC 30190:2021 updates and replaces earlier editions/amendments of ISO/IEC 30190 (including the 2016 edition and subsequent amendment) and is part of a suite of BD recording media standards (for example ISO/IEC 30191:2021 which covers triple‑ and quadruple‑layer BD‑R disks). Related documents include earlier corrigenda and amendments to ISO/IEC 30190 and companion standards that define volume/file structure and testing methods for optical media interchange.
