The Sony PHDV-186DM 186 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 evaporation technology and a diamond-like carbon protective layer.
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.
A lubricant ensures low friction and reduced head stain. With superior stability, tape damage is minimized.
