My wife picked up some kid's music CDs from the library. She wants to extract some music from them to put as background music for some DVDs she is making. The odd thing is that each of them have this obvious pair of metallic vertical strips about a sixteenth inch wide and about 3 inches long on either side of the center. She is afraid to put them in her computer for fear of these metallic strips will mess her computer.
Has anybody seen them before and know what they are? Thanks.
