W-VHS
From Wikipedia, the free encyclopedia
W-VHS is a high definition analog video tape format created by JVC. The format was introduced in 1994 and is no longer supported; the tapes are no longer manufactured and no players are currently produced for this format.
The recording medium of W-VHS is a 12.7 mm (½-inch) magnetic metallic tape stored in a cartridge the same size as VHS. The tape can be used to store 1080i or 480i analog signals (but not 480P or 720P). Audio is stored in the VHS HiFi or S-VHS Digital Audio formats.
Since W-VHS tapes are harder to find many people have been using the similar Digital-S (D-9) tape. While D-9 are still not that easy to find they are more available than W-VHS tapes in certain regions. JVC Professional even recommend the use of them for W-VHS. The runtime between W-VHS and Digital-S are not the same. A Digital-S tape with a a length of 64min is approx 105min or so.
