two-channel recording with a

specification, which features 720 effective

Compatible with Existing and New DV Videocassette Tape
As a member of the proven DV family of formats, the HDV format has, from
the outset, been developed for compatibility with all grades of DV videocassette
tape. This allows operators to use high-grade DV videocassette tapes for
applications where high robustness is critical, or consumer-grade videocassette
tapes for more economical operations. For heavy-duty applications, newly
developed high-grade PHDVM-63DM Mini Cassette tape, DigitalMaster TM ,
which is compatible with the HDV, DVCAM and DV formats, is available.
Long Recording Time
The HDV format adopts the same track pitch and tape speed as the DV format,
thus offering the same recording time – a maximum of 63 minutes on a mini
videocassette such as DigitalMaster tape.
