VARIED OPC TEST CD-R TCD-R071W For Checking CD Players, CD Recorders and CD Drives 1 ． Purpose TCD-R071W is designed for the operation (matching) check of CD Players, CD Recorders and CD Drives when it is used to play the CD-R its jitter and beta of the signals are varied by the different laser power at each tracks. Besides, it is simulated a deterioration of the organic dye which is the recording media of CD-R when it is exposed under sunshine or environment with high temperature and high humidity. 2 ． Disc Specifications（TCD-R000RMR） ・Organic dye ： Phthalocyanine group ・Reflecting ratio ： Rtop 0.65 or more （by our standard measuring equipment） ・Disc capacity ： 650Mbytes ・Disc type ： 74min. ( for Audio ), for 8X speed ・Scanning velocity ： 1.2m/sec ・Track pitch ： 1.6 micro meter 3 ． Recorded contents TNO 1 2 3 4 5
Contents Lch : 1kHz 0dB Rch : 400Hz 0dB

TOTAL TIME (Including pause time) 10:10 ＊1 ： Laser power meet specified jitter value in this specifications on TNO.2~4. ＊2 ： Jitter shown above is measured by 3T method. ＊3 ： Beta(%) is the value for reference. ＊4 ： RF Level (V) is the value for reference. Each value mentioned *2~*4 is measured by ALMEDIO standard measuring equipment. Attached actual data.
Do not write on the surface with a pencil, ballpoint pen, or the like, and do not affix a sticker to the disc. Do not expose the disc to the direct sunlight nor leave it in a place with high temperature or humidity. After playing, store it in its own case.
