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 DigitalMasterTM PHDVM-63DM. 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.
