Notes
• Hitachi Maxell single sided discs (HG type in the case of DVDs) have
been confirmed to be compatible with this camcorder and are
recommended. Take care not to dirty (including fingerprints) or scratch
the surface of the discs when handling.
When using a double-sided disc, take great care with handling it. Using
non-Hitachi Maxell discs may not allow the camcorder to deliver optimum
performance.
• DVD housed in a square cartridge/caddy case or a round DVD holder
cannot be used as is. The DVD must be removed from its case/holder
before it can be used.
Note on BD-R/DVD-R
This camcorder writes control data to a disc in order to automatically make
recording adjustments when first recording after:
• a disc is inserted, and
• the power is turned on while the disc is in the camcorder.
If there is not enough space on the control area of a disc, recording may not
be possible even if the data space for recording movies is not full. To prevent
this, avoid performing operations described above more than 99 times per
disc.
Unusable Discs
Dual layer BD and DVD discs, BD-R LTH type discs (Dye Type), +R, and
HD-DVD.
