I sometimes record vinyl records on CDR for my dad so he can play his old music in his new truck.
I first used one of those dual deck audio CD recorders. I routed an aux cable from the receiver to the dual deck CD recorder onto an audio CDRW. I then copied the CDRW onto an audio CDR.
The audio CD recorder stopped working, so I used my desktop computer. I used a Y cable with RCA L/R at one end into the receiver and a stereo 1/8" plug into the blue line-in jack in the back of my computer. I used MusicMatch to record the audio into mp3, then burn the mp3s as a music disc with Easy CD Creator. However, it's a pain moving the computer and monitor to the room where the record player and stereo receiver are.
My bro just got a new laptop but it only has a headphone jack and a mic jack. I was told that the mic jack is the same as a line in jack when it's in a laptop, and that the computer will automatically switch the mic jack into line-in mode. It would be so much easier using the laptop to record the vinyl records instead of lugging the computer and monitor.
