Apparently that value comes from 75 sectors per second * 80 minutes...
75*80*60 = 360000, and of course, 360000*2048/512 = 1440000, although
it actually seems that it should be one sector less than 80 minutes, 
which is 359999 2048-byte sectors or 1439996 512-byte chunks.

BTW, there are/were also 90 and 99 minute 'CD-Rs' -- Wikipedia's page on 
CD-Rs describes them, but they were never very popular, and a lot of 
drives can't read the discs.
