   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 ...

   The larger storage capacity of a DVD-R compared to a CD-R is achieved by focusing the laser to a smaller point, creating smaller 'pits' as well as a finer track pitch of the groove spiral which guides the laser beam. These two changes allow more pits to be written in the same physical disc area, giving higher data density.

   The DVD Book also permits an additional disc type called DVD-14: a hybrid double-sided disc with one dual-layer side, one single-layer side, and a total nominal capacity of 12.3 GB. [60] DVD-14 has no counterpart in ISO. [49] Both of these additional disc types are extremely rare due to their complicated and expensive manufacturing. [60]

   BDXL discs store more per data layer, roughly 30 GiB, so they are able to store 100 GB in only three instead of four layers. No single-layer variant for BDXL exists, given that a first-generation BD-R DL disc already exceeds the capacity of one layer of a BDXL.

   Blu-ray Disc has a higher maximum disc capacity than HD DVD (50 GB vs. 30 GB for a double layered disc). In September 2007 the DVD Forum approved a preliminary specification for the triple-layer 51 GB HD DVD (ROM only) disc though Toshiba never stated whether it was compatible with existing HD DVD players. In September 2006 TDK announced a ...
