GigaStation is using their MMVF technology. I know it's expensive but it's the first VCR replacement that is going to hit the market. Everyone else is claiming to get to 4.7 gigs but that is still not enough. You need at least 5 gigs. Anyway prices have a way of coming down as you all know. NEC Corp. is another company that will propose a proprietary rewritable format. NEC will begin shipping a sample of the 5.2-Gbyte Multimedia Video File (MMVF) disk system. NEC developed the original version of this format in 1996 and has been fostering the disk system as MMVF. "NEC has already shifted MMVF from a laboratory project to a business project," said an NEC spokesman. MMVF's specifications resemble those for DVD disks. It employs a 12-cm diameter disk with two 0.6-mm-thick phase-change disks bonded, a 640-nm laser and land-and-groove track recording. NEC claimed that the 5.2-Gbyte density was achieved mainly by the development of new PRML (partial response, maximum likelihood) signal-processing technology, which makes it possible to record in narrower-pitch tracks. NEC plans to ship a bare-drive sample to set manufacturers, including its internal set-manufacturing section. "Some set manufacturers may build a video recorder using the drive as the core," said the NEC spokesman. "We are participating in discussions at the DVD Forum and may be involved in future format making, but at present, NEC will concentrate on MMVF promotion."
