The CD player doesn’t play CD’s I’ve burned on my home computer. Why not?
The reason for this has to do with the disc reflection rate. Molded CD’s (CD’s purchased with the music already on them) have a reflection rate of 0.8 to 1.0, CD-R (CD’s you burn that are read only) are 0.6 to 0.8 and CD-RW (read/write CD’s) are .15 to .25. The CD players’ ability to read data off the CD is limited by the Servo Signal Processor (SSP) of the equipment. The SSP of the DMC1CD unit only guarantees to read a CD with a reflection rate more than 0.8, it will marginally read a disc with a reflection rate between 0.6 to 0.8 (which is why, occasionally, you may be able to play ones you burn). So any CD with a reflection rate less than 0.6 cannot be read and will not play.
In addition the speed at which the CD is burned will have an effect on play back. The faster it is burned the more difficult it is to replay.
And finally the age of the laser burner affects playability. The laser burners degrade over time and can cause reader faults.
Note: music DVD’s will not play in your CD player. Please check discs that you try to play to ensure they are CD’s and not DVD’s.
