Information technology - Digitally recorded media for information interchange and storage - 120 mm triple layer (100,0 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 100,0 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: - the one disk type; - the conditions for conformance; - the environments in which the disk is to be operated and stored; - the mechanical and physical characteristics of the disk, in order to provide mechanical interchange between data processing systems; - the format of the information on the disk, including the physical disposition of the tracks and sectors; - the error-correcting codes and the coding method used; - the characteristics of the signals recorded on the disk, enabling data processing systems to read data from the disk. This document provides for interchange of disks between disk drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing systems.

Overview - ISO/IEC 30193:2021 (BD rewritable disk, 120 mm triple layer, 100.0 Gbytes)

ISO/IEC 30193:2021 specifies the mechanical, physical and optical characteristics, signal quality, data format and recording method for a 120 mm triple-layer Blu-ray (BD) rewritable disk with a capacity of 100.0 Gbytes. The standard enables reliable interchange of digitally recorded information by defining disk geometry, environmental conditions, conformance rules and read/write signal characteristics so that user data can be written, read and overwritten multiple times.

Key topics and technical requirements

• Disk type and capacity: Single disk type defined - 120 mm triple-layer BD rewritable, 100.0 Gbytes per disk.
• Mechanical & dimensional characteristics: Reference planes, overall dimensions, clamping zones, transition and rim areas to ensure mechanical interchangeability.
• Environmental and durability requirements: Specified test, operating, storage and transportation environments, plus cover-layer durability (impact, scratch resistance, fingerprint repulsion).
• Optical characteristics & reference drive: Optical beam parameters, refractive indices, reflectivity, birefringence, measurement velocities and normalized servo transfer functions to support consistent reading/writing.
• Data format and coding: Physical track/sector layout, data frame and block structure, addressing and control data. Error control topics (error-detecting codes, LDC and BIS blocks/clusters, interleaving) are defined to support robust data recovery.
• Conformance & compatibility: Conditions for conformance, generating and receiving system requirements, and compatibility statements to allow disk interchange among systems.

Practical applications - who uses this standard

• Optical disk manufacturers: For designing and manufacturing 100 GB triple-layer BD-RW media that meet mechanical, optical and durability requirements.
• Drive and firmware designers: To implement optical systems, servo controls and read/write channels that conform to reference drive parameters and signal characteristics.
• Test and certification labs: For verifying conformance to dimensional, environmental and signal quality requirements.
• Systems integrators & IT procurement: When specifying removable optical media for backup, distribution or long-term interchange between data processing systems.
• Digital preservation and archival projects: As part of a validated media strategy where rewritable optical media is used for data interchange and controlled overwrite capability.

Related standards

ISO/IEC 30193:2021 is intended to be used together with standards that specify volume and file structure to provide full data interchange between systems. For practical implementation, implementers should reference relevant file-system/volume standards alongside this optical-media specification.
