When you bring in multiple tapes, reels, etc. and they are shorter than 80 minutes in length we can often combine more than one source on to one CD. You may have, for example, a cassette that you only recorded a few minutes on or have a few records to transfer. This is a way to save you some money and reduce the number of disks you have. Keep in mind that no matter how many sources we transfer from and put on one CD they can’t be any longer than 80 minutes to fit on the playable CD.
