Ricoh recordable Blu-ray disks : Ricoh has developed recordable disks for Blu-ray Disk and HD DVD, the next-generation DVD formats, and starts shipping samples to hardware manufacturers. The Ricoh samples to be shipped are BD-R and HD DVD-R, write-once disks for Blu-ray Disk and HD DVD respectively. They have a capacity of 25 GB (BD-R) and 15 GB (HD DVD-R), approximately three to five times that of current disks. By employing highly sensitive inorganic recording materials and high-precision stampers newly developed for next-generation recordable DVDs, Ricoh was able to achieve high reliability when writing and reading data. This will provide an advantage in further speed increases and multilayer structures.
