ISO IEC 29171:2009 pdfダウンロード。Information technology — Digitally recorded media for information interchange and storage — Information Versatile Disk for Removable usage (iVDR) cartridge
1 Scope
This International Standard specifies the dimensional, mechanical and physical characteristics of an information Versatile Disk for Removable usage (iVDR) cartridge to enable mechanical interchangeability between data processing systems. Hard disk drive technologies can be used in the cartridge.
This International Standard specifies the environment in which iVDR cartridges are to be operated and stored,and specifies the dimensions and pin assignments of a connector employed by iVDR cartridges to enable data interchange.
Together with ISO/IEC 24739-3 and a standard for volume and file structure, this International Standard enables full data interchange between data processing systems.
Figure 1 shows an external view of an iVDR cartridge.

4 Conventions and notations
4.1 Representation of numbers
A measured value is rounded off to the least significant digit of the corresponding specified value. For instance,it implies that a specified value of 1,26 with a positive tolerance of + 0,01 and a negative tolerance of – 0,02 allows a range of measured values from 1,235 to 1,275.
Numbers in decimal notations are represented by the digits 0 to 9.
Numbers in hexadecimal notation are represented by the hexadecimal digits 0 to 9 and A to F in parentheses.
The setting of bits is denoted by ZERO and ONE.
Numbers in binary notations and bit patterns are represented by strings of digits 0 and 1.
4.2 Names
The names of entities, e.g. specific sides, are given a capital initial, except for iVDR.
