Yes, it's purely to maximise storage capacity in the case of CDs, because the
data rate is constant (16 x 2 x 44100) bits per second, plus CIRC (error
correction) overhead.  The most efficient use of space is when the disk passes
under the laser at the optimal linear speed - for audio, the speed which
produces the above bitrate, when the data is packed as tightly as it can be. :)
