Assuming the then output voltage as VpP and the dark output voltage as V odP , sensitivity R pP is defined according to the following formula. R pP = | VpP - VodP | / 6 W *7 50 W DC light is radiated to the center of each photodiode at 50m . Assuming the then output voltage as VpR and the dark output voltage as VodR , sensitivity V pP is defined according to the following formula. R pR = | VpR- VodR | / 50 W *8 Take measurement assuming the mode switching terminal voltage on V MP/R =0V in the playback mode and V MP/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 20s after change of the mode switching terminal voltage. Take measurement with 20 W DC light radiated to the center of each photodiode at 50 m. Assuming the then output as Vp and dark output voltage as Vod , sensitivity R p is defined according to the following formula. R p = | Vp- Vod | / 20 W q Please refer to the chapter "Precautions for Use". (Page 78 to 93) Common to both modes Recording mode Playback mode |
