What are you talking about? Phonographs records have spiral grooves of
varying depths which affect the output of the magnetic pickup. CDs has
pits (and lands), which are the physical equivalents of zeros and ones.
See the article extract below.

>From Wikipedia: CD manufacturing is the process by which commercial
discs are replicated in mass quantities using a master created from a
source recording. This may be either audio (CD-Audio) or data (CD-ROM).
This method is used in the mastering of CDs, and does not include blank
CD-Rs or DVDs, although these are made using similar methods.

A compact disc (CD) can be used to store audio, video, and data in
various formats which are defined in the Rainbow Books. A CD is usually
manufactured in a class 100 or better clean room or self contained
clean room on the finishing line. A CD can usually be manufactured
within strict manufacturing tolerances for US$1 or less.

CD mastering differs from burning in that the pits and lands of a
mastered CD are moulded into the CD, rather than being 'burn marks' by
a CD burner.

If blank CD-Rs do not use dyes on the recording side, you can post what
method is used by blank CD-Rs to store information. If you write that
the dye on the recordable surface is impervious to heat, say from hot
wax, you will get a lot of laughs.
