Notes on Power Supply and Video Cassettes

Usable cassettes

For recording in the HDV/DV format, we recommend you use a DigitalMaster™ cassette such as standard HDV/DVCAM/DV cassette (PHDV-276DM, etc.), or mini HDV/DVCAM/DV cassette (PHDVM-63DM, etc.).

For recording in the DVCAM format, we recommend you use a standard DVCAM cassette, Mini-DVCAM cassette, or DigitalMaster™ shown above.

using DVCAM recording on the same tape will be two- thirds of the time available when HDV/DV (SP) recording is used.

Cassette memory

Some mini cassettes and standard cassettes have the cassette memory ( mark). The unit, however, does not support the cassette memory function.

However, if you use the DSR-25/45/50 as a recorder, the unit accesses cassette memory only if the recorder is set

to [AUTO ].

To save a recording

To prevent accidental erasure of a recording, set the REC/ SAVE switch on the cassette to SAVE. To record or dub audio on a tape, set the switch to REC.

Cassette compatibility

A DV format cassette tape can be used for HDV. The recording bit rate and recording track pitch on a tape of the HDV1080i system used for the HVR-M25AU/ M25AN/M25AE/M25AP are about 25 Mbps and

10 µm, respectively. The specifications are the same as those of home use DV (SP) tapes. The recording time on an HDV tape is also the same as that of a DV (SP) tape. The track pitch of DVCAM is 15 µm, which is 1.5 times that of HDV/DV (SP). Therefore, the recording time
