Among other things, Sony Optiarc supplied the Blu-ray drives for the Sony PlayStation 3. The naming scheme for the drives is as follows: DDU stands for DVD-ROM, AD stands for DVD-RW, BR for BD-ROM and BC for BD Combo. A combo drive is a drive that only supports the newer format in reading and the predecessor in writing.
For rewritable CD-RW, DVD-RW, DVD+RW, DVD-RAM, or BD-RE media, the laser is used to melt a crystalline metal alloy in the recording layer of the disc. Depending on the amount of power applied, the substance may be allowed to melt back (change the phase back) into crystalline form or left in an amorphous form, enabling marks of varying ...
DVD±R/W (also written as, DVD±R/RW, DVD±R/±RW, DVD+/-RW, DVD±R(W) and other arbitrary ways) handles all common writable disc types, but not DVD-RAM. [1] A drive that supports writing to all these disc types including DVD-RAM (but not necessarily including cartridges or 8cm diameter discs) is referred to as a "Multi" recorder.
Mount Rainier can be used only with drives that explicitly support it (a part of SCSI/MMC and can work over ATAPI), but works with standard CD-R, CD-RW, DVD+/-R and DVD+/-RW media. The physical format of MRW on the disk is managed by the drive's firmware , which remaps physical drive blocks into a virtual, defect-free space.
Both CD-R and DVD-R outperformed all forms of Blu-ray disc in regards to longevity: the best performing Blu-ray disc, the BD-RE (rewritable Blu-ray) has an average longevity of 20-50 years, while non-rewritable BD-R discs have an average longevity of 10-20 years under ideal conditions.
Furthermore, XCP.Sony.Rootkit installs a device driver, specifically a CD-ROM filter driver, which intercepts calls to the CD-ROM drive. If any process other than the included Music Player (player.exe) attempts to read the audio section of the CD, the filter driver inserts seemingly random noise into the returned data, thus making the music ...
Those 74 minutes come from the maximum playtime that the Red Book (audio CD standard) specifies for a digital audio CD (CD-DA); although now, most recordable CDs can hold 80 minutes worth of data. The DVD and Blu-ray discs hold a higher capacity of data, so reading or writing those discs in the same 74-minute time-frame requires a higher data ...
Free software implementations often lack features such as encryption and region coding due to licensing restrictions issues, and depending on the demands of the DVD producer, may not be considered suitable for mass-market use.
