Lens That Writes on Both HD-DVD and Blu-Ray 289

Posted by ScuttleMonkey from the one-lens-to-rule-them-all dept.
morpheus83 writes "Ricoh claims they have developed an optical component that reads and writes all disk formats -- Blu-ray Disc and HD-DVD, as well as DVD and CD -- with one pickup and one objective lens. The component is a 3.5-mm diameter, 1-mm thick round diffraction plate with minute concentric groves on both sides which function as a diffraction grating. Based on disc information the drive can identify which format disk is loaded, Ricoh's optical diffraction component adjusts the laser beam with its diffraction grating for each format and passes it to the objective lens."

    Phew! I thought there'd be no solution to the format wars.

    Oh wait, there's still:

    • cable wars (HDMI, component)
    • DRM wars (broadcast flag and more)
    • HD wars (DLP, LCD, Plasma, i vs p, etc.)
    • provider wars (comcast, DISH, DirectTV)
    • DVR wars (comcast (ick), DISH (ick), DirectTV (ick), TIVO (yea!))
    • did I mention DRM wars? (it's worth mentioning more than once)
    • compression wars (have you looked closely at the quality of a comcast HD broadcast?, and/or their OnDemand?)
    • price wars. (players, recorders (if you get permission to record), media (if you get permission to play))

    But, at least now we've gotten that pesky dual-compatible use-a-single-object-lens issue out of the way. Now I can tell all my friends and family the hurdle has been cleared and to let the floodgates of new consumers open.

    Not.

      Holy crap, one format war to another!

      The following will generate a flamewar in rec.bicycles.tech that go on for months:

      Shimano or Campagnolo?
      What about mechanical vs hydraulic disc brakes?
      Caliper, Cantilever, Centerpull, Coaster, disc, Double pivot, Drum, Roller, Rollercam, Roller lever, Sidepull, Single pivot, Spoon brakes?
      Low spoke count wheels vs 32 or 36 count?
      Tubular or Clincher tires? What about Tufo?
      Octalink or square taper spindle?
      British, Italian, French, Swiss, or Raleigh threading?
      130 vs 110 mm BHC?
      Hook or no hook rims?
      Does a wheel hang by its spokes or stand on its spokes?
      Disc wheels or spoked wheels?
      Hard Anodizing or plain? Does hard anodizing weaken aluminum?

      And that's just to start.

      • It's just like the "format wars" in general aviation:

        High wing vs. low wing

      • what worried me about the format war wasn't the pissing match between geeks over what's the best, it was the prospect of buying the 'wrong' format and having to shell out for a new player and buy all my movies again (or shell out big bucks for what's now a specialty item to play what I've already bought, anyone try to buy a betamax lately?). With tape at least you had to rebuy your favs everynow and then since the tapes wear out, disks don't really do that.

      To be fair, the so-called DRM war is a valid point, just not with the examples you used. It's more of an iTunes M4P versus PlaysForSure protected WMA thing. DVDs have macrovision, CSS, region coding and more, not one or the other, and the HD formats are or will be the same way. Likewise for cable wars, but it would be HDMI vs DVI vs that new HDMI-esque thing for computers that doesn't have the crazy licensing fee. Aside from that, it's either two separate entities or market competiton (which is a good thing, unless you LIKE monopolies).

      Now back to cleaning out my room.
    • Most of these are hardly "wars". Just consumer choice.

      If you buy an LCD, it won't become obsolete when Plasma "wins the war" (wtf?)

      Similarly for most of those items. My Toshiba PVR will still be useful if TiVo wins some sort of war.

      On these three, you seem to be saying that non-competition is good for consumers.

    From the article:

    Although the diffraction device works for both reading and writing modes, Ricoh will initially offer the device for disk players only. Because some laser beam energy is lost at the grating, using the diffraction device for recording will require a blue laser with higher power than those used in conventional recorders.

    It's a good start. Legal issues may end up being the biggest hurdle.

    So, if Blu-ray players are expensive as hell, and HD-DVD players are also expensive (though not quite as much), wouldn't a player that combined the capabilities of the two be even more expensive? Unless these things can be produced relatively cheaply, then this isn't going to be the answer to the format war.
    • No, not necessarily.
      I think the main factor behind the price of the new formats is the fact that the companies CAN charge a billion dollars per unit.
      Those units have one laser, and a couple lenses made to read only one type of data.
      Combining the technologies really isn't that hard in concept.

    This kind of multi-numerical aperture diffractive lens has already been used in several DVD players for CD compatibility. As an example, check out this link [pentax.co.jp].
    Notice that you do not only need different numerical aperture lenses to read every format, you also need to generate lasers of the proper wavelengths. There are several solutions for this, but the easiest is to use three different laser diodes.

      Why do you need to use the correct wavelengths?

      Blueray discs use blue lasers because the pits are smaller than the wavelength of the infrared laser used for CDs. But why would that stop you reading a CD with the blue laser? The wavelength is still smaller than the pits so all you'd be doing is seeing the pits in a higher resolution, right? (or am I missing something?)

      Virtual monopolies are needed (especially in formats) to help consumers eventually.

      PCs took off because Windows provided an equal format for everyone.
      Apple thrives in spite of this monopoly by maintaining its own monopoly through its OS, regulating everything in order to keep quality high and survive as a 'niche' demographic just as concerned with design and appeal as they did utility. Having a virtual strangehold on internet music helped too.

      The only place where these 'format wars' have had even minimal success have been in game consoles, because they were largely seen as competing factions to a toy, instead of a 'universal medium' like office software or movies. If we get back to the point where we only have a couple of key consoles (I predict Nintendo will successfully splinter off, leaving the main war between MS and Sony), so much the better for game programmers.

Furthermore, multi-format drives don't necessarily signal death to single-format drives. I know a lot of people still using DVD-R/w and DVD+R/W drives, even though DVD+-R/W drives cost the same amount.

Eventually, somebody ALWAYS starts combining them all together, so a few years after adoption, everything supports everything. DVD players that you can get in the grocery store for $49.99 play audio CD's, MP3 CD's, DVD single layer, DVD dual layer, DVD +R, DVD-R, DVD +RW, etc. Hell, My $100 PS2 does even better than that.! (I use My PS2 exclusively for entertainment. Love how easy it is.) As long as there's no physical difference in the format, the digital differences amount to just a few lines of code, which ends up being very cheap to combine on a tiny chip, even after those licensing fees. As long as the media doesn't physically change, there will be increasing convergence all of the time. Eventually, those cheap players that you can get at Wal-Mart will read HD, Blu-Ray, OGG, and WMA's. Just give it time. It'll happen.
