Overview

To achieve recording at levels of density at 7.5m2/bit required for the Digital BETACAM format, Maxell brought together its extensive expertise in developing advanced metal tape technology and cassette mechanisms for professional broadcasting applications. The result: Maxell Digital BETACAM videocassettes for high-density component digital recording.

Maximum Performance

Thanks to Maxell’s exclusive Multi-Orientation Technology and advanced dispersion systems, our high output Ceramic Armor Metal Particles reach their full energy potential, improving the tape’s C/N ratio a full 2dB more than our popular BETACAM SP tape. In addition, the Particles’ tough Ceramic Armor coating ensures that output stays high because it protects against energy-dissipating heat, oxidation and corrosion.

High Durability Design

The combination of Ceramic Armor Metal Particles and Maxell’s special high strength binder makes a major contribution to increasing the tape’s rigidity - a factor that maximizes tape durability in demanding playback modes such as shuttle and still as well as improving compatibility with archiving and post-archival playback. Long-term reliability is raised even higher by the videocassette’s dust, heat and shock-resistant high electro-conductivity shell.

Self-Cleaning Technology

Advanced filler dispersion technology, used for Maxell’s D-2 digital videocassette, keeps the head surface clean.

Smooth Tape Travel

The backcoating used in Maxell’s new “Digital BETACAM” tape has been carefully designed to optimize smooth tape travel. What’s more, Maxell’s patented SW (Smooth Winding) reel makes a major contribution to reducing tape degradation because it delivers unmatched packing of the tape, especially in high-speed shuttle modes.
