A：iVDR is a compact, lightweight, portable, removable, large-capacity recording media. Its high-speed access capability makes it possible to record at twice the speed of a Blu-ray disc (BD-RE). Adoption of SAFIA content protection technology enables the high-speed recording and moving of digital content. The standardization of iVDR technical standards makes it possible for iVDR to be widely adopted, from AV to ICT and in-vehicle equipment.
A：iVDR is an acronym of information Versatile Device for Removable usage, which means a portable information device designed for various applications.
A：Cartridge dimensions, mechanical and electrical interface specifications and recording method have been established as “iVDR standards.” iVDR hard disks are compatible with various kinds of equipment. 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.
A：The iVDR (Standard) is 110 mm long, 80 mm wide and 12.7 mm thick. It is similar in size to a passport. The iVDR Mini is 67 mm long, 80 mm wide and 10 mm thick, while the iVDR EX is 126 mm long, 80 mm wide and 18 mm thick.
A：There are currently four standard iVDR types available: 500 GB, 320 GB, 250 GB and 160 GB. 500 GB is equivalent to about 107 DVD discs (single-sided single-layer type = 4.7 GB per disc), or about 20 Blu-ray discs (single-sided single-layer type = 25 GB per disc). The capacity of hard disks is increasing by some 40 percent annually, and accordingly iVDR capacity is also expected to increase annually. A 1TB iVDR is expected to be launched in 2011.

A：Because its interface and recording method have been standardized, the iVDR hard disk can be used with all devices compliant with iVDR standards, from computer equipment to AV-related devices.
iVDR-S (iVDR-Secure) type is the only removable hard disk that can record copyright-protected digital broadcast content. This content can be read and overwritten on other compatible devices.
A：We recommend the iVDR-S type, which employs SAFIA content protection technology. The iVDR-S type uses encryption to record digital broadcast content. The iVDR-S type and related equipment carry the product logo

A：SAFIA (Security Architecture For Intelligent Attachment device) is content protection technology for digital TVs and digital audio presented by the SAFIA license group. SAFIA has been adopted in removable disks for the first time ever. Also, it is approved as a “content protection method for removable recording media (iVDRs) that are mountable on a receiver” by Dpa (The Association for Promotion of Digital Broadcasting).
A：There are two types of iVDR: iVDR-S has content protection capability, while iVDR has no content protection capability. iVDR-S complies with SAFIA content protection technology, enabling the recording and moving of digital broadcast content.
iVDR-S: Secure-type iVDR with content protection capability
iVDR: Non-secure-type iVDR
A：No, there aren’t. Cartridges and devices that do not carry the logo do not comply with SAFIA content protection technology and therefore cannot record digital broadcast content. However, they can record analog broadcast content.
A：Yes, it can. Through the use of an optional USB adapter, you can connect an iVDR to a PC. Similar to external storage devices, iVDR can read and write data once it has been formatted. Both iVDR types can be used as external hard drives.
A：It takes about 7 minutes, twice as fast as with a Blu-ray disc (about 15 minutes*), to move a one-hour terrestrial digital high-definition program from a built-in HDD to an iVDR-S.
*BD-RE double-speed media
A：There is no difference between iVDR and Blu-ray in picture quality. Both of them are recording media which does not influence the picture definition of TV programs. When you record TV programs in the same high-definition mode, you will get the same picture quality.
A：Hitachi, Ltd. releases "Wooo" series TV with an iVDR slot. Hitachi Maxell, Ltd. and I-O Data Device, Inc. have launched "iVDR Player", Hitachi Maxell, Ltd. and SANYO Electric Co., Ltd. have launched "iVDR Recorder" with digital tunar function.
As for media, "iVDR-S"; a recording media of full-spec high definition and "iVDR"; an additional hard disk or a back-up media are available from Hitachi Maxell, Ltd. and I-O Data Device, Inc. iVDR-S-compliant PC adapter will be released soon from I-O Data Device, Inc.
