REV PRO™ media and drives are specifically designed

and developed to meet the requirements of video pro-

fessionals and their desire to migrate to a complete file-

based workflow. REV PRO’s revolutionary Removable

Rigid Disk (RRD) technology combines the benefits of

hard drive technology (speed, reliability, and non-linear

access) with videotape (portability, ease of use, and low

cost). The end result is an extremely durable and reliable

medium, fully supporting professional video workflows.

REV PRO media provide fast random access to video

clips. Files can be edited and moved around easily—just

like a hard drive. REV PRO media are well suited for

high-speed data transfers and perfect for true HD acqui-

sition and editing. Its enhanced multi-segment caching

delivers dual-stream performance to allow for simultane-

ous read and write access. REV PRO is ideally suited for

everyday video, graphics, and/or rigorous field produc-

tion applications. It is a medium that is flexible and can

be readily re-purposed in any file-based workflow. There

are currently two lines of REV PRO media and drives:

The REV PRO 35 line and the REV PRO XP/ER line.

REV PRO combines the best of both worlds: the portability and
ease of use of tape, with the non-linear access capabilities of
hard drives.

REV PRO provides dual stream performance for
simultaneous record and playback or real-time cross
dissolves in editing environments.

Storage Capacity

REV PRO media have the storage capacity of up to

80 minutes of HD and up to 4 hours of SD material,

depending on the chosen codec and bit rate. High

performance, sustained data rates allow for real-time

record/play capability directly from the media. REV PRO

allows users to record and play back two simultaneous

HD streams with enough added bandwidth for audio and

metadata.

Durability

REV PRO media use standard 2.5-inch laptop hard drive

components, but are engineered for much greater dura-

bility and reliability by placing only the magnetic medium

and motor within the removable cartridge and adding

additional redundancy to the medium. The drive’s heads

and electronics remain in the drive assembly.

The media can be used in harsh environments and are

resistant to damage within extreme operating tempera-

tures, dust, wind, moisture, high altitudes, shock, and

™

vibration. The Grass Valley
