Cost Advantages / Disadvantage DISADVATAGE: Because the recording layer in a Blu-ray disc is 0.1 millimeters below the surface on the top of a 1.1 millimeter substrate, this disc will require a new production line.

ADVATAGE: Because HD-DVD discs are almost physically identical to current DVD discs, the same production lines can be used to produce both discs, saving the expense of building new factories, says Masato Ootsuka, senior manager of the engineering development department at optical disc maker Memory-Tech.

DISAVATAGE: Development of a common head for both DVD formats still not done

Stragtegy Blu-ray Disc supporters plan to include interactive features and game capabilities to discs that hold high-definition movies.

The Blu-ray Disc camp is targeting recording of high-definition programs, but this could hamper it in markets where high-definition programming has yet to take off.
The HD-DVD team is seeking victory through the backing of entertainment companies for prerecorded content and hoping users are more interested in watching such content than time-shifting television.
Intial Cost Estimate $2,700 $1000
Media Cost Estimate $40 $?
Misc. Notes

Some believe that it would be possible for the low-bit-rate and blue laser technologies to co-exist, the former being positioned as a playback format for pre-recorded HD-DVD movies and the latter as a recording format for real-time interlaced TV programs, including HDTV programming.

While HD-DVD offers a lower data storage capacity than Blu-ray Disc, HD-DVD can store more high-definition programming. That's because it uses the MPEG4.AVC, which is based on the H.264 codec; and the VC9 codec, which is based on Microsoft's Windows Media 9 codec.
