Not quite.   Do the math:

72 minutes of 44.1KKz stereo 16-bit audio takes 762,048,000 bytes.  That's
the raw capacity of the CD, WITHOUT the leadin, TOC and whatnot.

Yet a 72 minute CD only can handle 650MB of data.  

That's because (mode1) data CDs have 2,048 byte sectors, when the raw
sector size of a CD is about 2,300 bytes.  This is used for error
correction and whatnot.

When cdrecord calculates the space required, it gives you the raw size,
not the size of the data.
