The dual-layer strength of Blu-ray high definition video technology has already seen its 25GBs per layer capacity quash the resistance of format pretender HD DVD – and now that strength is to be reinforced thanks to advancements made by Sony and Panasonic.
More pointedly, with the 2010 Consumer Electronics Show (CES) looming large on the calendar, heavyweight market giants Sony and Panasonic have revealed a new data evaluation technique that could lead to Blu-ray discs holding up to 33.4GBs per layer for a total storage count of 66.8GBs.
The technique in question, called i-MLSE (or Maximum Likelihood Sequence Estimation), has been created to better gauge optical quality when used during read and write processes, thus allowing both Blu-ray readers and burners to deal with up to a third more capacity, while Hollywood distributors could pack their releases with longer movies and more related content.
According to a report posted via Tech-On, the introduction and implementation of i-MLSE does not require that device manufacturers create new laser components in order to take advantage of the data storage improvement – mainly because the technique is largely dependent on software as opposed to hardware.
However, the report also notes that processing hardware within certain Blu-ray drives may need to be tweaked as the improvements associated with i-MLSE are reliant on boosted performance in real time.
Although neither submitted to nor approved by the official Blu-ray Disc Association, Sony Corp. is expected to formally table i-MLSE for possible inclusion to the existing Blu-ray standard.
And, given Sony’s core positioning within the development of Blu-ray, it’s hard to see the association not green-flagging such a worthwhile format improvement.
