Converting cassettes to CDR



I am new to this site and definately a newbie

I have a PII 700 with CD ROM and CDRW drives and am experimenting burning with both CDR and CDRW media.

With Adaptec DirectCD I am OK with audio CDs but need help to convert old cassette tapes to CDR.

I saw posted here where it was decribed how to burn LP’s using a Radio Shack converter plugged into the headphone jack. Would this work for me?

Any help would be appreciated
