swatkat said:CD and DVD look same, that's where the similarity ends....this has been said 100s of time.....
see, in CD writers the Laser used to write/read data on CD has a wavelength of 780nm.....but the Laser that's used to write/read DVD in a DVD Writer has a wavelength of 650nm.....
so using a laser of smaller wavelength, more data is crammed into the Disc.....
Also, some other specs like Pit Length, Track Pitch will be smaller in DVDs when compared to CDs......
kunwar said:IS it possible that the laser waveength will get more reduced or have we reached the maximum limit? Also in a DVD Writer is only the laser different or are the other equipments also different as in is it possile to replace the 780 nm laser of VCD with 650 nm laser for DVD?(i dont think so but whats the harm in getting another opinion/s)
