DVD-RAM MASTERING GENERATOR

DA-3380

REQUIREMENT FOR OPTICAL CUTTER

Dual beam drive

It is necessary to drive two laser spots to record the data in the

embossed data area and rewritable area.

LOCK signal

The rotation control function of CAV is necessar y follow the

reference signal from the unit.

START signal

Beginning of the signal generation is detected from the radius

position of the disc and the function to output the beginning

timing to the unit is necessary.
