To search without cassette memory
When you use a cassette without cassette memory, the
unit searches in the order of the actual positions of the
scenes, regardless of the setting of CM SEARCH on
the CM SET menu.
On a cassette with cassette memory, when you want to
perform searches with this procedure, set CM
SEARCH on the CM SET menu to OFF.
For details on the CM SET menu, see "CM SET menu" on
page 58 (GB).
Note
Title search is not available when searching a cassette
without cassette memory.

Notes
• The unit cannot detect a signal for Index search or an
unrecorded portion within 20 seconds of the
beginning of the playback.
• When you intend to turn the unit off, press the STOP
button on this unit to stop the tape transport operation
beforehand. If you turn the unit off while a tape is
running, for example, by using an AC timer, the unit
or the tape may be damaged.
• The editing software used on the digital non-linear
editing system may mark an index signal on a tape
itself. Therefore, if you use a tape on which signals
transmitted from a digital non-linear editing
controller are recorded or a copy tape made from one,
using digital dubbing, Auto Repeat may not be
performed correctly.
To stop Auto Repeat
Press the STOP button on this unit.
To release the Auto Repeat mode
Set the TIMER selector on the front panel to OFF.

(GB) Chapter 2 Playback and Recording
The unit starts searching backwards or forwards
until the number comes to zero, then plays back the
scene. During Photo search, the unit turns to the
playback pause mode.
How signals are recorded
There are four different signal types, one for each
search method; index, title, date and photo signals.
They are recorded by the digital camcorder (DSR-200/
200P, 200A/200AP, PD100/PD100P, PD100A/
PD100AP, PD150/PD150P, 250/250P, etc.). However,
the type of signal recorded and where it is recorded (on
the tape or in the cassette memory) depend on whether
the cassette has cassette memory or which type of
video equipment is used for recording. Please note that
if the signals for a certain search type are not recorded,
you cannot perform that type of search. For details on
the signals used for a particular type of search, refer to
the instruction manual of the recorder.
Signals that can be recorded on this unit are as follows.
Signals for In cassette memory On tape
Index search* Yes Yes
Title search No No
Date search No Yes
Photo search No No
* If AUTO INDEX on the VTR SET menu is set to ON and the
unit is in the stop mode, when you start recording, the unit
automatically marks a signal for Index search. If AUTO INDEX
During recording,
is set to OFF, the unit does not mark it.
pressing
the INDEX button on the unit or the INDEX WRITE
button on the Remote Commander marks a signal for Index
search regardless of the AUTO INDEX setting.
Notes
• If you record another program over the beginning of
the search signals, you will not be able to locate the
original program.

• You cannot add search signals after recording.
To add a search signal for Auto Repeat, start
recording from the point where you want to add it.
• When recording on this unit, signals for Index search
do not have information on the day of the week.
• Searching may not be done correctly if the tapes were
not recorded on Sony-brand digital video equipment.
About the cassette memory
• A tape with the mark has cassette memory. When
using the 16 kbit cassette memory, you can store up
to 135 search signals. (The number changes
depending on the memory capacity of various
cassettes. It also changes depending on the data size
combination of index, title, date, photo, and tape label
data stored on a tape.) This unit is capable of storing
and retrieving up to 16 kbits of information in
cassette memory.
• To locate scenes that did not fit in the cassette
memory, or to locate scenes in order of their position
on the tape, set CM SEARCH on the CM SET menu
to OFF. You can use the same procedure to search for
a scene on a tape without cassette memory.
For details on the CM SET menu, see "CM SET menu" on
page 58 (GB).
Note
The number of search signals that you can record is
limited by the cassette memory space available when
you start recording. When you use a previously
recorded tape for repeated recordings, make more
memory space available by erasing unwanted items
using ITEM ERASE or ERASE ALL on the CM SET
menu before you start recording.
Automatically playing back a tape
repeatedly (Auto Repeat)
This unit can repeat the playback of all or a part of the
tape.

Set the TIMER selector on the front panel of this
unit to REPEAT.

Recording

This section describes the connections, settings and
operations necessary to perform recording on this unit.
The same settings and operations apply whether you
are using the unit for dubbing or as a stand-alone
recorder.
Connections for Recording
To digital video equipment with a DV jack
The video and audio signals are sent with hardly any
degradation, enabling high-quality recording. The
signal flow is automatically detected so you do not
need to make separate connections for input and
output. Also, connecting the unit to an editing
controller via DV jacks, you can configure a digital
non-linear editing system.
For connections of the editing controller and this unit, refer
to the editing controller instruction manual.

The unit rewinds the tape to its beginning, and
starts playback automatically. The unit repeats the
playback from the beginning to the first index (if
there is no signal for Index search on the tape, to
the next unrecorded portion; if there is no
unrecorded portion, to the end of the tape).
Auto Repeat using an external AC timer
If you connect an external AC timer (not supplied) to
this unit, you can repeat playback automatically at a
preset time.

Notes
• With the DV connection, the sound is recorded in the
same audio recording mode as that of the source tape.
To record in a different audio recording mode from
the source tape, use the analog connection instead.
• With the DV connection, data codes (recording date/
time, camera data) recorded on the source tape are
transmitted to the recorder (this unit). As a result,
when you play back a recorded tape on this unit and
press the DATA CODE button on the Remote
Commander, the same data codes as those recorded
on the source tape are displayed on the monitor
screen. However, the contents of the cassette memory
are not transmitted. If you want to transmit the
contents of the cassette memory, use the duplicate
function.
• If no picture appears via the DV jack, disconnect the
i.LINK cable (DV cable), then reinsert it straight.
• If the editing software used has the capability to
output the time code as well as the video and audio
signals from the digital non-linear editing controller
to this unit, and you intend to record that time code,
set DV IN TC on the TC/UB SET menu of this unit
to EXTERNAL.
For details on the TC/UB SET menu, see "TC/UB SET
menu" on page 56 (GB).
• When DV IN TC on the TC/UB SET menu is set to
EXTERNAL, if you input time code that is not
continuous or does not advance correctly to the DV
jack, the value of the recorded or displayed time code
may not be equal to the actual value of the input one.
If you use a tape recorded in such condition, you may
not be able to perform search or edit, depending on
the devices you use.
• For connection of the editing controller and its
peripheral devices, refer to the instruction manual of
the editing controller and that of the editing software
you use.
• Edit functions are specified by the editing software.
For details on the editing methods used, refer to the
instruction manual of the editing software.
• When connecting a device that has a 6-pin DV jack to
this unit, first, connect the plug of the cable to the 6-
pin DV jack.
