iVDRs are categorized as cartridge types and built-in types. Specifications for the body shape, connector shape and interface specifications (signals, electrical characteristics, command set) have been standardized.
There are three iVDR cartridge types: Mini, Standard and EX. Each has both iVDR-S with SAFIA and iVDR versions.
|iVDR Mini||iVDR （Standard）||iVDR EX|
Note)The name of "iVDR Xtreme" has been changed to "iVDR EX" as of August 6th, 2009.
Note)In October 2009, iVDR (Standard type) was approved as international standard by the ISO/IEC* and released as the International Standard “ISO/IEC 29171”. We now can maintain compatibility among iVDR cartridges not only in Japan but also worldwide.
Unlike the cartridge type, the iVDR built-in type does not have a sheath case and is designed to be used inside media equipment, although it is still removable. The iVDR built-in type, which incorporates SAFIA, has three different-sized hard disks: 1.8 inch, 2.5 inch and 3.5 inch. It is designed to boost the capacity of built-in hard disks and enable digital TVs and hard disk recorders to remain up-to-date.

The diagram below shows the physical layer, interface layer, file system layer and application format layer of iVDR specifications. When all layers from the physical layer to the application layer are implemented, interoperation between digital TVs and audio equipment is possible.
Design and specifications are as of October 28, 2009.
