The easiest way is to purchase a pioneer cd recorder
Its simple to use, just plug in the line outs to the lines in and presto you have your own cd.
I have a yamaha 8 track cassette recorder (mt8x) and for the past 6 years have been able to record quality
demo's direct to cd (pioneer pdr05, the very first one made) This has been a cheap way of gaining gigs for both myself and friends
Or if you allready have a computer with a CD writer in it, record the output of your tape with your computer. The quality will depend on the quality of your soundcard...
This will also allow you to edit the recording with software tools, and if you purchase a quality soundcard, to directly record to your pc.
