ISO/IEC 13346-1:1995

ISO/IEC 13346-1:1995 Information technology —

Volume and file structure of write-once and rewritable media using non-sequential recording for information interchange — Part 1: General

The international standard ISO/IEC 13346 defines the file structure of optical discs used for information storage and interchange. It is commonly known as the UDF standard. The standard was developed by the Optical Storage Technology Association (OSTA) and first published in 1995.

What is ISO/IEC 13346-1:1995?

ISO/IEC 13346-1:1995 is an international standard that defines the volume and file structure of write-once and rewritable media using non-sequential recording for information interchange.

The standard was developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) and was first published in 1995.

The standard is intended to provide a consistent, interoperable format for storing data on write-once and rewritable media. It is also intended to be used as a basis for developing application-specific standards.

ISO/IEC 13346-1:1995 is divided into two parts:

Part 1: General
Part 2: Specifications for implementation

Part 1 of the standard defines the overall structure of the volume and file system, while Part 2 provides specific details on how the system should be implemented.

What are the requirements of ISO/IEC 13346-1:1995

ISO/IEC 13346-1:1995 provides the requirements for a volume and file structure of write-once and rewritable media using non-sequential recording for information interchange.

The standard defines a logical block address (LBA) as the means of specifying the location of data on the media. LBAs are used to identify both files and extents within files.

Extents are a contiguous set of sectors within a file, and are the smallest unit of data that can be read or written.

ISO/IEC 13346-1:1995 also defines the concept of a virtual disk, which is a abstract representation of a media. A virtual disk consists of one or more virtual partitions, each of which is mapped to a physical location on the media.

partition on the media.

Virtual disks allow for the easy creation of multiple views of the same data, without having to physically duplicate the media.

What are the benefits of ISO/IEC 13346-1:1995

ISO/IEC 13346-1:1995 is an international standard that provides guidelines for the volume and file structure of write-once and rewritable media used for information interchange. The standard was developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

The benefits of ISO/IEC 13346-1:1995 include improved compatibility between different write-once and rewritable media, as well as better support for data interchange between different computer systems. The standard also helps to ensure that data stored on write-once and rewritable media can be read by a wide range of devices, including computers, DVD players, and CDROM drives.
