I have very limited hard drive space (for now anyway while I save up dough) is it possible to use 100 MB zip disks or CDRs/CDRWa to store my projects (eight tracks of music) and then mix down to a CDR? Do I just need to face reality and shell out the money now for another hard drive? I use a PC based recording system but I know that one of the Roland portable units uses 100MB zip disks as a means of storing data. I wanted to know if I could do the same.
