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 Rewritable disk

This document specifies the mechanical, physical and optical characteristics of a 120 mm rewritable optical disk with a capacity of 25,0 Gbytes or 50,0 Gbytes. It specifies the quality of the recorded and unrecorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks. User data can be written, read and overwritten many times using a reversible method. This disk is identified as a BD rewritable disk. This document specifies the following: - two related but different types of this disk; - conditions for conformance; - environments in which the disk is to be operated and stored; - mechanical and physical characteristics of the disk, which allow mechanical interchange between data processing systems; - format of the information on the disk, including the physical disposition of the tracks and sectors; - error-correcting codes and coding method used; - characteristics of the signals recorded on the disk, which enable data processing systems to read data from the disk. This document provides for interchange of disks between drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing systems.

Overview

ISO/IEC 30192:2021 specifies the mechanical, physical and optical characteristics of 120 mm BD Rewritable (BD-RE) optical disks with capacities of 25,0 Gbytes (Single Layer) and 50,0 Gbytes (Dual Layer). The standard defines signal quality, data format and the reversible recording method that enables user data to be written, read and overwritten many times. Its purpose is to ensure reliable information interchange between drives and data processing systems when used together with a companion volume and file structure standard.

Key topics and technical requirements

• Disk types and capacities: Single-layer (25,0 GB) and dual-layer (50,0 GB) BD Rewritable disks.
• Conformance and compatibility: Conditions for conformance, requirements for generating and receiving systems, and a compatibility statement for interchangeability.
• Environments: Specified test, operating, storage and transportation environments to guarantee disk performance and durability.
• Mechanical and dimensional characteristics: Reference planes/axis, overall dimensions, clamping zones, mass, moment of inertia, dynamic imbalance, axial and radial runout.
• Optical characteristics: Transmission stack thickness, refractive index, reflectivity, birefringence and angular deviation of recording/reading layers.
• Reference drive and measurement: Requirements for a standardized reference drive, optical beam, HF read channel, servo characteristics and measurement velocities.
• Data format and recording: Physical disposition of tracks and sectors, data frames, scrambled frames, error-detection (EDC), error-correcting codes (ECC), LDC (low-density parity) and BIS clusters, addressing and user control data.
• Signal characteristics: Quality metrics for recorded and unrecorded signals to enable reliable readback by compliant drives.
• Durability and safety: Cover layer scratch/impact resistance, fingerprint repulsion, and flammability/safety considerations.

Practical applications and who uses this standard

ISO/IEC 30192:2021 is essential for:

• Optical media manufacturers designing BD-RE substrates, layers and cover coatings.
• Drive and firmware engineers implementing read/write channels, servo systems and error-correction compatible with BD-RE media.
• Test labs and QA teams verifying conformance to mechanical, optical and signal quality limits.
• System integrators and archival specialists ensuring media interchangeability and long-term reliability for data distribution, backups and archival storage.
• Standards bodies and regulatory organizations referencing a harmonized specification for Blu-ray rewritable media.

Related standards

• ISO/IEC 30192:2021 is intended to be used with a companion volume and file structure standard (for example, UDF) to provide full data interchange between systems. Implementers should also consult related optical disk and file-system standards used in Blu-ray ecosystem design.
