ML drives? edit

Where can I buy ML drives and discs? There should be at least working prototypes somewhere, I think. Henri Tapani Heinonen 09:40, 2 August 2005 (UTC)Reply

There were working prototypes edit

Working prototypes were demonstrated at several trade shows, but good luck in finding one. My guess is they ended up in storage somewhere in Silicon Valley (think of the ending scene from Raiders of the Lost Ark). Joe Newman 17:10, 17 November 2005 (UTC)Reply

Technology section edit

I added this section because the article really needed a picture showing what ML is. Here's a critique of my own contribution in case it inspires others:

  • The ML marks in the diagram are so colorful as to be confusing. Unfortunately in plain grayscale, they were difficult to distinguish by eye.
  • The facts are personal knowledge; I didn't do a good job referencing them.
  • Can it be proved that "the technique had not been seriously pursued in data storage prior to Calimetrics"?

Sanyo's HD-Burn edit

Is HD-Burn at all related to ML? From Sanyo's page http://www.digital-sanyo.com/BURN-Proof/HD-BURN, it doesn't sound like it.

It's not ML, but I suppose it is related. The Calimetric ML CD-R format incorporates three techniques: smaller pits (600nm vs 830nm), more efficient error correction (RS vs CISC) and, of course, MultiLevel modulation (8 levels vs. 2). As I understand it, HD-Burn is just the first two techniques without ML. Summary Spiel496 04:16, 16 July 2006 (UTC)Reply
