ISO/IEC 30190 specifies mechanical, physical, and optical characteristics of a 120 mm recordable optical disk with a capacity of 25.0 Gb or 50.0 Gb.
ISO/IEC 30190 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.
ISO/IEC 30190 gives technical specifications such as terms, conformance, conventions and notations, general description of the disk, reference drive, dimensional characteristics, mechanical characteristics, optical characteristics in the information area, data format, physical data allocating and linking, the layout of recordable area of information zone, etc., for 120 mm Single Layer (25.0 Gbytes per disk) and Dual Layer (50.0 Gbytes per disk) BD Recordable disk.
ISO/IEC 30190 provides for the 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.
ISO/IEC 30190 on Digitally recorded media for information interchange and storage is useful for:
The BDA sent project proposals for the international standardization of four formats, as it was needed for keeping the compatibility of the removable medium in the market, and to check that the disks and devices can satisfy the specifications.
ISO/IEC 30190 specifies the technicalities for three related but different types of this disk, that is, the conditions for conformance, the environments in which the disk is to be operated and stored, the mechanical and physical characteristics of the disk, so as to provide mechanical interchange between data processing systems.
ISO/IEC 30190 also provides information about 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 help users to read data from the disk.
ISO/IEC 30190 describes the quality of the recorded and unrecorded signals in the format of the data, and the recording method, thereby allowing for information interchange by means of such disks.
