*6 6µ W DC light is radiated to the center of each photodiode at 50µm φ .
Assuming the then output voltage as VpP and the dark output voltage as VodP , sensitivity R pP is defined according to the following formula.
RpP= | VpP- VodP | / 6 µ W
*7 50µ W DC light is radiated to the center of each photodiode at 50µm φ.
Assuming the then output voltage as VpR and the dark output voltage as VodR , sensitivity VpP is defined according to the following formula.
RpR= | VpR- VodR | / 50 µW
*8 Take measurement assuming the mode switching terminal voltage on VMP/R =0V in the playback mode and VMP/R =Vcc in the recording mode.
*9 Sensitivity response characteristics after mode switching between the playback and recording modes is specified in the sensitivity in 20µs after change of the mode switching
terminal voltage. Take measurement with 20µ W DC light radiated to the center of each photodiode at 50 µmφ.
Assuming the then output as Vp and dark output voltage as Vod , sensitivity R p is defined according to the following formula.
Rp = | Vp- Vod | / 20 µW
