ISO/IEC 16963:2017(Main)
Information technology — Digitally recorded media for information interchange and storage — Test method for the estimation of lifetime of optical disks for long-term data storage

ISO/IEC 16963:2017 specifies an accelerated ageing test method for estimating the lifetime of the retrievability of information stored on recordable or rewritable optical disks. The method is based on the theoretical assumption that the lifetime of data recorded on an optical disk has a lognormal distribution. Detailed testing is specified for the following formats: DVD-R/RW/RAM disks, +R/+RW disks, CD-R/RW disks and BD recordable/rewritable disks. The testing can be applied to additional optical-disk formats with substitution of the appropriate specifications and can also be updated by the committee in the future as required. ISO/IEC 16963:2017 includes: - stress conditions: - Basic and Rigorous stress-conditions for testing and subsequent analysis using both the Eyring and Arrhenius methods; - ambient storage conditions in which the lifetime of data stored on optical disk is estimated: - a Controlled storage-condition, Temp = 25 °C and RH = 50 %, representing full-time air conditioning. The Eyring method is used to estimate the lifetime under this storage condition; - a Harsh storage-condition, Temp = 30 °C and RH = 80 %, representing the most severe conditions in which users handle and store optical disks. The Arrhenius method is used to estimate the lifetime under this storage condition; - a description of the evaluation system; - procedures for specimen preparation and data acquisition; - definitions and methods used in testing specific disk types; - analysis of test results to determine the lifetime of stored data; - a format for reporting the estimated lifetime of stored data. The methodology includes only the effects of temperature and relative humidity. It does not attempt to model degradation due to complex failure mechanism kinetics, nor does it test for exposure to light, corrosive gases, contaminants, handling, or variations in playback subsystems. Disks exposed to these additional sources of stress or higher levels of temperature and relative humidity are expected to experience shorter usable lifetime.

Imaging materials - Optical discs - Care and handling for extended storage
ISO 18938:2014

This International Standard establishes general principles for the care and handling of digital optical
discs during use. It addresses the issues of physical integrity of the medium necessary to preserve access
to the recorded data (information). This International Standard includes recommendations for handling
procedures to maximize the effective life of optical discs. Faulty handling, packing and transporting
techniques and methods often cause physical damage to the discs and to the content recorded thereon.
Extending the longevity of optical discs requires the identification of appropriate handling methods, as
well as well-developed and implemented training programs.
For the purposes of this International Standard, the term “optical disc” includes the families of compact
disc (CD), digital versatile disc (DVD), high definition digital versatile disc (HD DVD) and Blu-ray disc
(BD)1), and any hybrids of these families. The term “optical disc” also includes each type of disc within
a family, including injection moulded [read-only memory (ROM)], dye-layer [recordable (R)] and phase
change [rewritable (RW, RE), random access memory (RAM), and recordable (BD-R)] technologies.
While some of the recommendations in this International Standard (e.g. those for staff training) apply
specifically to large-scale or long term usage, the basics of all recommendations in this International
Standard are intended to be applied in circumstances where the desired result is long-term usage of the
medium whether archival, commercial or personal.
This International Standard does not cover magneto-optical (MO) discs, laser discs (LD) or glass discs.
At the time of writing, International Standards do not exist for HD DVD and Blu-ray discs. Nonetheless,
it is believed that the recommendations in this International Standard for care and handling can equally
apply to them. It is recognized that some of these requirements are not necessarily possible for the
individual user to achieve.
The following are within the scope of this International Standard:
— use and handling environments, including pollutants, temperature and humidity and light exposure;
— contamination concerns;
— inspection;
— cleaning and maintenance, including cleaning methods and frequency;
— transportation;
— disasters, including water, fire, construction and post-disaster procedures;
— staff training.
The quality of the data written on the disc is outside the scope of this International Standard. However,
a high quality result of the recording phase is important to the longevity of information. It is advisable
that a rigorous program of data integrity testing be implemented, as this forms an obligatory part of
all digital long-term storage. In addition, when keeping digital information for archival purposes, it is
advisable that a multiple copy/multiple location strategy be in place.

This International Standard specifies - the conditions for conformance testing and the Reference Drive; - the environments in which the cartridges are to be operated and stored; - the mechanical, physical and dimensional characteristics of the cartridge, so as to provide mechanical interchangeability between data processing systems; - the format of the information on the disk, both embossed and user-written, including the physical disposition of the tracks and sectors, the error correction codes, the modulation methods used; - the characteristics of the embossed information on the disk; - the magneto-optical characteristics of the disk, enabling processing systems to write data onto the disk; - the minimum quality of user-written data on the disk, enabling data processing systems to read data from the disk. This International Standard provides for interchange between optical disk drives. Together with a Standard for volume and file structure it provides for full data interchange between data processing systems.

Information technology — Volume and file structure of write-once and rewritable media using non-sequential recording for information interchange — Part 3: Volume structure

ISO/IEC 13346 specifies a format and associated system requirements for volume and boot block recognition, volume structure, file structure and record structure for the interchange of information on media between users of information processing systems. The media shall be recorded as if the recording of sectors may be done in any order. Note 1 - The medium is not restricted to being of only one type; the type of medium may be either write once, or read only, or rewritable, or a combination of these types. ISO/IEC 13346 consists of the following five Parts: Part 1: General Part 2: Volume and Boot Block Recognition Part 3: Volume Structure Part 4: File Structure Part 5: Record Structure Annex A - ICB Strategies, is part of ISO/IEC 13346-4. This part of ISO/IEC 13346 specifies a format and associated system requirements for volume structure by specifying: the attributes of a volume and the descriptors recorded on it; the relationship among volumes of a volume set; the attributes of a partition of a volume; the attributes of a logical volume and the descriptors recorded on it; levels of medium interchange; requirements for the processes which are provided within information processing systems, to enable information to be interchanged between different systems; for this purpose, it specifies the functions to be provided within systems which are intended to originate or receive media which conform to this part of ISO/IEC 13346.

Information technology — 120 mm DVD rewritable disk (DVD-RAM)

This International Standard specifies the mechanical, physical and optical characteristics of a 120 mm optical disk to enable interchange of such disks. It specifies the quality of the recorded signals, the format of the data and the recording method, thereby allowing for information interchange by means of such disks. The data can be written, read and overwritten many times using the phase change method. This disk is identified as DVD-RAM. This International Standard specifies - two related but different Types of this disk (see clause 7), - the conditions for conformance, - the environments in which the disk is to be tested, operated and stored, - the mechanical, physical and dimensional characteristics of the disk, so as 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, - the characteristics of the signals recorded on the disk, thus enabling data processing systems to read the data from the disk. This International Standard provides for the interchange of disks between optical disk drives. Together with a standard for volume and file structure, it provides for full data interchange between data processing systems. The optical disks specified by this International Standard may be enclosed in cases according to ISO/IEC 16825 as specified therein.
