This may seem like an odd question. Truth is that I was thinking of doing a program that could burn a two tone picture in the reflective part of a CD-R disc (yin-yang symbol, happy face, etc.), to be used as a decoration or souvenir.
Of course the technical implications of such an idea are overwelming me. Any documentation regarding the phisical representation of bytes in the CD program area is welcome. Some questions:
- Is there some way to write raw data bits in the program area without using data block separation, subchannel bits, etc. (to make the picture smoother)?
- If not (or even if so) is there a way to tell how many frames (or bytes) can be written in a full turn (360Âº) of the CD? Are there more sectors (or bytes) in the outter part of the CD than in the inner?
- I have read that the bits representation in the CD is a NRZ inverted. Is this true in all cases?
- Am I wasting my time and should stop right now thinking about an inviable project?
Thanks in advance.
