Originally known as Digital-S, it was given the designation D-9 by SMPTE in the spring of 1999. D-9 uses a 50 Mbps
compression scheme which has been widely recognized by the engineering community as the blueprint for digital production and broadcasting.
Taking advantage of our experience and leadership in 1/2" tape and transport technology, JVC formulated a unique 1/2"
tape that permits the recording of a vast amount of data and offers additional strength and reliability. The metal particle tape used by all D-9 products offers an unbeatable combination of high
performance and reliability, supported by powerful error correction that can even replace missing data in the unlikely event of a tape dropout. Even with a clogged head D-9 may continue to play back
Up to 124 minutes of recording is possible with a single tape and the high durability of the tape itself means that
it can be reused several hundred times without noticeable performance deterioration - making D-9 an even more economical choice. In addition to a 124-minute D-9 cassette, JVC's robust line
of dustproof D-9 cassettes also includes lengths of 10, 34, 64 and 104 minutes.
