DVD Challange? Don't think so... (Score 1)

Tapes suck independent of whether or not they record in a digital format.

• Digital tapes are still sequential, not random access.
• Digital tapes will still degrade with every use (though the resulting distortion will be different).
• Digital tapes are still mechanical; all moving parts must be functioning within spec for reading or writing to take place.
• Because they are sequential, digital tapes are extremely impractical for interactive software. Interactivity is one capabilities that makes DVDs so successful.

That said, digital tapes do make sense for home recording. But then, so don't hard disks...
