Hmmm.... Your 7500 can't be very old, so unless it is a buggy drive (or model edition) it should have no problems reading a full 80 Min./700 MB CD-R. (I would think!) However, keep in mind that a 700 MD CD-R does not pose a problem to an older 650 MB max. drive *until* you exceed the old drives ability to read. If your earlier burns have been under the 650 MB mark (which I believe 8.2's were), a 650 MB CD-ROm drive would never let you know that it can't go further, even when using the higher capacity medium. Shane mentioned it best on that matter. See his post shortly after yours. It could be that your combo drive really is limited to 650 MB. Did you ask tech support about its read capacity, and did you check the documentation that came with your laptop? This could be your answer.
As long as you have a replacement drive coming in, wait until it does and see if anything changes. You may get a newer drive with an increased read capacity. Meanwhile, I am going to stick my recently burned MDK 9 CDs into a CD-ROM drive that I know cannot read beyond 650 MBs and see if I can reproduce your problem. Catch you afterward...
