Then, when I have extra blank CDs, I'll simply drag that disk image to Toast and a new CD-ROM will pop out a few mintes later. A full CD will only take about ten minutes or so. All computers for the last five years have CD players standard. You can format all the above for use in PCs. You can't listen to music Zip, Jaz, or Orbs in your car.
CDs take much less space to store a large collection.
