The cassettes have the same dimensions and construction as the cassettes used in 8 mm video format recorders and camcorders. Until the advent of AIT, Exabyte was the sole vendor of 8 mm format tape drives. The company was formed with the aim of taking the 8 mm video format and making it suitable for data storage.
The D9 is a series of heavy tracked-type tractors, carried on continuous tracks and usually used as bulldozers. The series began in 1954 with a prototype tractor called the D9X. Ten D9X prototype models were built in 1954. In 1955, the 286 hp (213 kW) D9 was introduced to compete against the more powerful Euclid TC-12.

The Navistar DT (Diesel Turbocharged or Diesel Turbo) engine family is a line of mid-range inline-6 diesel engines.With horsepower ratings ranging from 170 hp (130 kW) to 350 hp (260 kW), the Navistar DT engines are used primarily in medium-duty truck and bus applications such as school buses, although some versions have been developed for heavy-duty regional-haul and severe-service applications.
DVCPRO HD, also known as DVCPRO100 and D-12, is a high-definition video format that can be thought of as four DV codecs that work in parallel. Video data rate depends on frame rate and can be as low as 40 Mbit/s for 24 frame/s mode and as high as 100 Mbit/s for 50/60 frame/s modes. Like DVCPRO50, DVCPRO HD employs 4:2:2 color sampling.
The tape is 1/2 inch wide, the helical scan head drum is 62 mm in diameter, and the video tracks, which are read by the video heads in the head drum, are 20 microns wide. [5] Video quality is generally very high; at standard definition, D-9's quality is comparable with Digital Betacam. [ 6 ]
Rear view of a W-D 9, showing the low profile compared to row-crop tractors. The McCormick-Deering W-9 departed from the letter series parallel, using much more powerful engines from International Harvester's crawler tractors, and heavier drivetrains. The W-9 was first produced in 1940 with the C335 engine used in the T-9 crawler.
