Sony Digital Master for HDV/DVCAM (PHDV-276DM)

• The Sony PHDV-276DM 276 Minute Digital Master Videocassette is a professional videotape with 2 active magnetic layers, improving carrier to noise ratio by 2.5db for 95% fewer errors and 60% fewer dropouts than consumer DV tape.
• It uses AMEII metal
• Digital master videocassette is a professional tape designed for mastering and is also highly flexible and convenient media, enhancing compatibility between camcorder and VTR.
• AMEII metal evaporation technology has been used to improve the packing of grains inside the magnetic layer, increase tape retentivity (Br) and output as well as achieve better C/N and error ratios
• Quality control has been enhanced following a complete review of the production process, resulting in improved drop-out figures.
• Diamond-like Carbon protective layer on the tape surface-a dramatic improvement in wear resistance-has been achieved, resulting in reduced head wear.
