High Quality Data CDs, Dual-Layer DVDs and Dual-Layer BDs for Testing CD, DVD and Blu-ray Drives
The Test BD is a world first for the effective testing of Blu-ray Disc Drives. It is a dual-layer disc offering 50GB of storage. The Test DVD is a DVD-9 which means that it is a single-sided double-layered disc offering 8.5GB of storage. The Test CD contains 700MB of data. All discs are manufactured by pressing (not burning) because pressed discs offer a higher level of reflectivity compared to burnt discs. Higher reflectivity leads to higher reliability and less read errors.
How do they work? These test discs contain a number of files which completely fill each disc. Each file contains a pre-determined sequence of binary data. This same data sequence has been programmed into BurnInTest so that when the disc is read each byte can be checked to see if it is the correct value. If an incorrect value is read, BurnInTest flags this as an error.
Compatibility
Note: Blu-ray is sometimes incorrectly referred to as "Blue-ray Disk", but Blu-ray Disc (BD) is the correct way to capitalize and spell this format.
Other notes The CD is a CD-ROM and does not contain music data. Thus it can not be played on a normal Hi-Fi music CD player (That is to say, it is only suitable for use with computer PC CD players). The DVD is a DVD-ROM and but does not contain video. Thus it can not be played on a normal DVD player connected to a television. It can only be used on a PC DVD player. The BD is a BD-ROM and contains only data. It cannot be played in a normal Blu-ray video disc player connected to a television nor a PS3. It can only be used on a PC Blu-ray player. None of the above media contains the BurnInTest software. The software must be downloaded from the PassMark Software web site. |
