36 Recording and Playback Loop Recording
When two or more P2 card slots contain cards, this
function allows the target P2 card to be switched in order.
Even when the free space of a P2 card is used up, this
function continues recording while erasing existing data.
To use this function, the menu option LOOP REC MODE
must be set to “ON” The option LOOP REC MODE can be
found in the <REC FUNCTION> screen on the SYSTEM
SETTING page. ‹ Notes
z When the loop recording capability is used, each P2
card must have at least one minute of free space.
z During loop recording, the P2 CARD ACCESS LEDs for
all target P2 cards illuminate in orange. Note that if any
of the target P2 card is removed, loop recording stops.
z When the menu option LOOP REC MODE is set to ON,
the viewfinder and display window both show “LOOP”.
However, when only one card is inserted, or when each
card has less than one minute of free space, the loop
recording capability does not work, even if the option
LOOP REC MODE is set to ON. If this is the case, the
indication “LOOP” flashes in the viewfinder and on the
display window.
z When the menu option LOOP REC MODE is set to ON,
the P2 card remaining free space indicates the minimum
guaranteed recording time.
The minimum guaranteed
recording time means the guaranteed time or length of
recorded data when LOOP REC stops immediately after
deleting old data.
z During recording of IEEE1394 input or INTERVAL REC
operation, LOOP REC is not available.
You can terminate the loop recording mode by either:
z Turning off the POWER switch of camera-recorder; or
z Setting the menu option LOOP REC MODE to “OFF”.
It is possible to record in intervals of one frame as the
shortest length by using the internal memory of the unit.
To use this option, open the REC FUNCTION screen from
the SYSTEM SETTING page, and set the interval recording
mode, REC TIME, PAUSE TIME and TAKE TOTAL TIME for
the menu option INTERVAL REC MODE. When the settings
are finalized, TOTAL REC TIME needed on the P2 card is
automatically calculated and displayed.
The following are the options for INTERVAL REC MODE:
OFF:
No interval recording performed.
ON:
Interval recording performed.
ONE SHOT:
Performs “one-shot” recording for the duration
specified under the REC TIME option by pressing
either the REC START/STOP button, REC button on
the handle, or VTR button at the lens.
‹ Notes
z When executing interval recording, data cannot be output
with IEEE1394. When the 1394 CONTROL is set to
[BOTH], it is also impossible to control external devices.
z The shortest recording time, stand-by time, and the set
value of the cut-off unit frame number*
1 may vary with
the recording method as follows.
*1 For instance, interval recording is at every 24 frames
since frames are cut off every two frames even if the
REC TIME is set to 1 second (= 25 frames) in the 25PN
mode of 720P.

Recording
Cycle 1
Data are recorded by connecting the unrecorded sections on
the P2 card (in the sequence of A to B to C). When the
remaining recording capacity is less than 30 seconds, A is
deleted, and data are record on C up to FULL (remaining
memory capacity is 0), and then new data are recorded (D).
