Having only made the jump to 33.4GB in January, electronics manufacturer Sharp has confirmed that it intends to launch the first commercially available 100GB capacity Blu-ray disc this month.
PC World reports that the units will go on sale in Japan on July 30th and are expected to cost in the region of $55-$60 each.
The launch of both rewritable 100GB discs and write-once 128GB discs is expected in the near future.
