In
analogue systems this generally involves recording longitudinal time code
on an audio track. Recommended level is -3
dB. Higher levels may cause distortion,
thereby degrading the signal while levels that are too low will also fail
because the next time code reader in the chain will not be able to recognize
the signal. Care must also be taken
that the time code track is clean of any other sounds.
Leaks from adjacent tracks can make the time code impossible to read.
A device which instantly
regenerates timecode to correct low level signals is called a refresher.
In
digital systems the time code will be generated internally by the device
so prestriping is usually not part of the process.
