Sanyo Develops 100GB, 12X Blu-ray Laser

By - Source: Tom's Hardware | B 11 comments

Sanyo this week announced that it has developed a new laser diode that emits a 450 mw (milliwatts) blue laser beam that can read information off of Blu-ray discs at 12X speeds — double what’s currently available. Best of all, it can also burn to Blu-ray writable discs at the same data rates, which is a huge time saver for heavy archival use.

Data throughput isn’t the only advancement that Sany claims. The company also said that because of its new diode design, it’s able to to read quad-layer Blu-ray discs, allowing manufacturers to produce Blu-ray discs that hold up to a whopping 100 GB of data. At this capacity, quad-layer discs can hold up to 8 hours of high-definition movies.

Currently, Blu-ray discs hold about 25 GB per layer for a total of 50 GB on a dual-layer Blu-ray disc.

Unfortunately, don’t expect to run to your nearest retailer and pickup a drive with the new laser. The development and standardization time required for Blu-ray devices are painstakingly long. Because of this, the likelihood of seeing the new high capacity Blu-ray drives out on the market is still one to two years away. By this time, who knows what will be available.

    Good going Sanyo!

    Decreasing the burn and read times for blu-ray is a must, if it is ever expected be used as a viable storage medium.

    Your not going to beable to write on a Quad layer
    disc. Only producing companys that embed the data onto the
    DVD will beable to benifit with this new technology. It's
    a great advance, but unless your going to put two movies
    on a dvd what is the purpose??? I had to laugh at one of
    the comments above about not haveing the need for Bluray. That's
    like saying you don't have the need for sleep. I am assumeing
    this person is still living in the stone age where credit
    cards and broadband and hair dryers doesn't exist. That or
    they actually believe that the future is direct downloads onto
    a very limited Settop box that produces less picture
    quality and is subject to data loss and other limitations.
    The future is bluray, the question really is, is when
    is it going to be affordable for the average Joe?????

    I just prefer to buy 2 1.5TB seagy HD's in raid 1. That's better than the steal price of blu-ray media.

    WORD, just buy hard drives and archive your shit in them, way cheaper for backup pruposes, raid then . hell even a NAS raid box is cheaper

    now for watching movies, yeah its cool, a blue ray player =D

    Agreed! Imo, this is not really aimed at the average person. This is better off being aimed at people with the need for the absolute best multi media setup (ie. need large HD content for displaying at events)

    Bluray is much slower than hard drives, also, a little scratch on the disk may make it unreadable or full of faults.
    Buy 3x1TB disks, they don't get (easily) scratched, and probably last longer than a Blu ray DVD disk.
