Panasonic 12 Minute DVCPro Videotape: AJ-P12M
- Narrow Tape - Big Performance: High-output metal magnetic particles deliver superb picture and sound quality on a tape just 6.35-mm-wide
- High Output, Low Noise: Ultra-fine metal magnetic particles provide a remanent magnetization of 370 mT (3,700 Gauss) and coercivity of 183 kA/m (2,300 Oe) for an output that's 5 db higher than older technologies.
- Dense Magnetic Pattern: A dense, ultra-thin 0.2 micron magnetic coating achieves exceptional low noise, high-frequency performance.
- Smooth Tape Transport: An ultra-smooth magnetic surface eliminates spacing loss and micro-dropouts resulting in low error rates and a high C/N (carrier to noise) ratio even in the higher frequencies.
- Excellent Durability and Reliability: A high-polymer binder on the magnetic layer assures maximum durability under repeated use, even after long storage periods.
- Protective Cassette Shell: A tough, sealed shell prevents entry of dust or other particles into the cassette. A reel-lock mechanism reduces tape sagging.
Notes about the DVCPRO format:
Data Rate and Running Time: DVCPRO, DVCPRO 50, and DVCPRO HD recording formats all use the same tape formulation. The difference is the amount of tape used to record the data. DVCPRO records at 25Mb/s, DVCPRO 50 at 50Mb/s, and DVCPRO HD at 100Mb/s. More data takes more space, so the tape has to run faster at higher data rates. Thus, a 12 minute DVCPRO tape would run just 6 minutes in DVCPRO 50 mode and only 3 minutes in DVCPRO HD mode.
Yellow Lid vs. Red Lid: To help users differentiate the format used to record a DVCPRO tape, manufacturers provide tapes that are color coded. Standard DVCPRO tapes are yellow. DVCPro HD tapes are red. Red or yellow, however, the tape is the same. It's just the labeling and naming that's different.
*High Definition LP Mode: DVCPRO equipment that is capable of recording in DVCPRO HD-LP mode (a.k.a EX format) utilizes a more precise record head that has the ability to record a track pitch that is only 9-microns wide. That is half as wide as the conventional DVCPRO record heads, which is 18-microns. Therefore, when using the DVCPRO HD-LP mode it is possible to double the record time without any loss of quality.
As of now, the only DVCPRO equipment that is capable of recording in the 9-micron mode are: AJ-HD1700, AJ-HD1200, and AJ-HD1400 decks as well as the new AJ-HDX-900 camera.
