Un disc cu o capacitate de 1000 de ori mai mare decat a unui Blu-Ray?

de Georgiana Niculescu | 25 mai 2010

Cercetatorii japonezi au descoperit o metoda prin care capacitatea unui disc obisnuit, stil DVD, poate fi marita de 1000 de ori. Este vorba de tratarea discurilor cu un strat metalic de oxid de titaniu, un material sintetic care ar conduce electricitatea atunci cand este expus la lumina, un fel de semi-conductor.

In timp ce inca mai asteptam lansarea Blu-Ray-urilor cu o capacitate de 128GB, japonezii ne promit ca in curand vom putea stoca pana la 25TB pe un disc. La momentul actual, pe un DVD obisnuit putem copia numai 4.7GB pana la 8.5GB de date, in timp ce pe un disc Blu-Ray putem stoca intre 25 si 50GB.

Totusi, diferenta dintre acestea si un disc cu o capacitate de 25TB este uriasa. Presupunand ca tehnologia se va dovedi a fi realitate si ca dezvoltatorii se vor ocupa si de lansarea echipamentelor de scriere si citire necesare, viitorul disc va porni cu siguranta o adevarata revolutie.

Desi momentan nu se stie nimic in legatura cu data la care discurile de 25TB vor deveni disponibile publicului larg, este putin probabil ca acest lucru sa se intample inainte de lansarea Blu-Ray-urilor de 128GB. Totusi, se pare ca tehnologia va deveni disponibila pentru comercializare in randul companiilor.

    Un roman a facut ceva de genul dar doar cu 10TB. Ideea principala e ca asta se intampla acum vreo 10 ani.

    25 de TB pe un disc, nu ai ce sa bagi pe el filme ai putea baga cam tot ce so scos din 2006 pana acum.

    25 de TB pe un singur disc, pai ar insemna sa scot HDD-ul de 500 de GB si sa-l fac unul exten/portabil apoi sa folosesc acest disc de 25 de TB in locul hard disk-ului

    Nu va avea succes. Nu este practic, va avea intrebuintari restrinse pt. anumite domenii, presupun.

    , I struggle to see the value pripositoon of this player priced at $700 to an educated consumer. It is quick, but not fast. It offers some neat features, but lacks what I consider the most meaningful non disc playback (ie Netflix). Its touted image enhancement features tend to render a synthetic image whose contrast and pop is delivered at the cost of relatively common jaggies. While some might prefer this image (especially on the smoothening engines of soem LCDs). I struggle to describe the overall image with its enhancing engines without using the word artificial or synthetic.My biggest criticism is not with the player but with its price. At $700, this player is grossly over-priced in my opinion (this is reflected in my 6.5 value rating). The LG BD390 offers very similar dvd performance and more features at half the price. For those looking for simply quality DVD and BD playback, the Pioneer 320 is its equal in most ways at nearly a third of its price. Sony missed an opportunity to introduce a class-leading player by introducing this player as is at $300 or $400 with netflix and other video-streaming features. Simply put, there are so many better options at this price point like an oppo and a roku or a lg 390 and a pioneer 320 both combined at lower the cost than this player!In the interest of comparing the 1000 against an established performer (Oppo) and a very popular player (LG), I thought I would provide some anecdotal commentary of their respective performance for SD DVDs. LG and Sony appear to use their own chipset while Oppo uses the ABT 2010. In regard to film cadence recognition, the ABT is one of the best and quickest. I noticed a rather unusual occurrence with the Sony. Unlike other second set lock-on recognition, the Sony seemed to require a few seconds to lock on in each set. This surprised me as it was relatively new to me in the repeating sequence. The Oppo requires lock on in the second sequence for 2:2 cadences, but once it locks on, it repeats without moire9. The Sony appears to repeat its recognition error on each set in a number of cadences.The Sony must have some very active edge enhancement that threw off its performance on vertical scrolling text. There was readily apparent shakiness or hesitation in movement as the text moved up the screen. This was different from the video deinterlacing I saw in some lower performing players. This text hesitation was also visible in some DVD's opening credits on film.For real world material, all three players do not differ that frequently to be perfectly candid. Only seldom does an interlacing appear. The Oppo offers realistic edge enhancement and fluidity in motion. The sony's edge enhancement is aggressive and does bring a more definitive contrast between images. That said, its enhancement does appear to come at the cost of fluidity and motion. This is probably a subjective area some folks might like the pop it brings and might play better on the high hertz lcds that sony makes. In the second chapter of killshot (with opening credits), I did see a minor jaggie in the bumper of the blue Cadillac with the LG and the Sony. This was not present in the Oppo (and the Marantz 7004). Edge enhancement was the strongest with the Sony in most scenes; this might be desirable for those looking for a very poppy image with a smoothening engine on an lcd. For me, I found it a bit unnatural on my plasma. Some details were enhanced at the cost of others ie the distinct lines of people against the scenery over-powered the details of their faces, predominantly in medium zoomed perspectives.Sony PQ adjustments:The overlaid display menu allows for +/-3 settings for the HD enhancer. It appears to have an impact on contrst and edge enhancement. I pasued a dark scene and noticed that the contrast between dark and light images was amplified with each increasing setting. The image revealed by the HD enhancer is brings out more detail as well and I think more HDish for most viewers. That said, it brings out a lot of jaggies. Back to kill shot for specific references in the third scene after the screen door moire, Mickey Rourke walks in a house with vertical paneling. To his right (screen left), you can see very noticeable jaggies on the vertical lines with +3. At the zero setting, thereis no moire. To an untrained eye, the +3 yeilds a better image. It bothers me with the amount of jaggies it creates.There is also a smoothening feature I was unable to see that big of a difference, but did detect slight tearing on fast motion with it dialed off the zero default position.Another note:The Sony had trouble with three of my burned DVD+Rs. Both the LG and the Oppo played them without issue. I tried some of the non-playing discs on my Marantz and Onkyo HD DVD player and both played them without issue. I am not trying to indict the Sony for poor error recognition of burned media, but I do want to pt this out.
