This is a Sony PHDVM-63DM DVCAM DigitalMaster Mini DV Cassette. It is compatible with any mini-DV or DV camcorder or VTR. This tape contains two magnetic layers that improve the carrier-to-noise ratio and produce 90% fewer errors than traditional DV tape. When recording in 16:9, more information is recorded versus 4:3 and there is greater possibility for errors. DigitalMaster reduces that risk by 90%.
