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, a new high-grade mini cassette
tape has been developed; the DigitalMaster
This tape is compatible with the HDV, DVCAM, and DV
formats.
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 when recording on a
DigitalMaster mini cassette tape.
