Maxell HDCAM 40 Minutes Tape B-40HD Maxell HDCAM Videocassette, attains HDTV recording by increasing recording density to 1.4x more than the Digital Betacam format, offering superior quality digital HD picture for a wide range of applications from transmission to HD ENG/EFP. This is enabled by its high mobility compact cassette size. The tape employs super-fine Ceramic Armor Metal magnetic particles. Combining this with multi-orientation technology to effectively utilize its high magnetic energy, the tape has achieved a high output and low noise ratio. Low error rate is also reached by achieving superior C/N characteristics
