DVD-RAM MASTERING GENERATOR DVD-RAM MASTERING GENERATOR DA-3380 OUTLINE DA-3380 is a signal source for making the master unrecord optical disc that satisfies the DVD-RAM standard. This unit provides the signal to make the all areas (embossed data area and rewritable area) of DVDRAM disc in accordance with data from the panel switches and the serial interface and supplies the signal to the optical cutter. 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. FEATURES 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. Option Applicable to 4.7 Gbytes SCSI 172 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. SPECIFICATIONS RF-1st signal (embossed area output) and RF-2nd signal (rewritable area output) Output range(TOP) Variable at 0 ~ Approx.+1.0V Output range(BOTOM) Variable at 0 ~ TOP level Setting resolution 2mV Output impedance Approx. 50 Ω Transmission clock FR-1st : 5.22MHz(450 rpm) RF-2nd : 5.50MHz ~ 12.94MHz (450 rpm) Frequency accuracy 20ppm or less Residual jitter 1ns or less Rise time and fall time 5ns or less Pulse width variable function Setting range Approx.-1T ~ Approx.+20ns Setting resolution 2ns Automatic switch at output level Switch by each T 3T ~ 14T Deflect signal (groove signal + header position control signal) Groove signal Variable at 0 ~ Approx.200mV Sine wave Output range Setting resolution 1 mV Output impedance Approx.50Ω Output frequency 29.58kHz ~ 69.57kHz(450rpm) Frequency accuracy 20ppm or less Distortion rate 1% or less(20mV ~ 200mVp-p) Groove end position correction Variable range : 3T ~ 7T(Standard value 5T) Setting resolution : 0.5T Output polarity switch output polarity is reversed Header position control signal Variable at 0 ~ Approx. ± 500mV, pulse signal Output range Setting resolution 2mV (Possible to set positive and negative individually) Rise time and fall time 20ns or less Output position adjustment (ID1,2) : 0 ~ + 4T in end position of groove, 0.5T step Output position adjustment(ID3,4) : 0 ~ + 4T in end mark of ID2, 0.5T step START/STOP signal (input) Input impedance Approx.47 kΩ Proper pulse width 10ms or less Logical polarity Active low LOCK signal (output) Output Line driver signal (pulse signal) Output impedance Approx.50 Ω Output frequency 15.75kHz Frequency accuracy 20ppm or less Duty ratio 50±10% Power source 100 ~ 240 VAC, 50/60 Hz Approx.16 W Case dimensions 190 (W) × 128 (H) × 350 (D)mm (projections not included) Weight Approx. 3.6 kg DA-3380 DVD-RAM MASTERRING GENERATOR 173 .
