The  time  code  is  used  when  the  time  code  signal
generated  by  the  time  code  generator  (time  code
signal  generator)  is  to  be  recorded  on  the  tape,  its
values are to be read by the time code reader (time
code signal reader), and the absolute position of the
tape  is  to  be  displayed  in  increments  of  hours,
minutes, seconds and frames.
The time code is written in the sub-code area (data
area) of the helical track.  This enables insert editing
to be conducted independently using the time code
alone.  In addition, the VTR’s playback speed can be
read from the stop mode to the slow motion playback
up  to  high-speed  playback  (approx.  50

k

normal

speed or approx. 100

k

normal speed when using a

DVCPRO tape).

The time code values are indicated on the display and
superimposed display.
