DA-3380

Generate the embossed data
      The unit automatically generated the signal to make the Pre-Pit (embossed data) for the Inside circumference on the DVD-RAM disc by connection with personal computer (RF-1st signal).
Record the groove and the pit of header part by the single beam one sequence
      The unit provides the RF-2nd signal to make the Header-Pit for rewritable area and the Deflect signal to make the groove on the DVD-RAM disc. Pulse width variable function
The pulse width variable function is provided to optionally correct
      The pulse width of the RF signal in accordance with characteristics of the optical cutter.
Automatically generates the signal
      The unit automatically generates the signal for cutting the disc from the inside circumference to the outside circumference.
Output voltage arbitrary set function
      The output voltage is arbitrarily set in accordance with each pulse in the RF signal.
Applicable to 450 rpm and 900 rpm
     The unit can be used with the optical cutter of the rotation speed 450 rpm and 900 rpm.
