I want to record songs from my PC to Mini-disc. How do i connect the player up to the computer and what leads do i need.

Depending on the model minidisk you use, you may or mayNOT be able to make a digital transfer.
However, all mini discks are capable of an analog transfer right from the headphone or line out jack on your pc.
Just use a wire from the line out on the pc .... into the line in ( rec in ) on the mini.

If you have a usb model, then a simple USB cable will do the trick !
