magnetic tape dj

alright i got this idea... im not sure from hearing about this women who made a shirt by weaving together magnetic tape and then attaching the 'magnetic reader' from a tape player to the end of a pen and rubbing it along the shirt.
-later i found out about Laurie Anderson, who did a similar project, attaching the magnetic tape to a bow and using it like a violin- she is a musician who has made cds and tours.
-I did a similar project (before i knew about laurie anderson, not that it matters) and took apart a tape player (below)


-isolated the 'reader' peice (below)

-i took clips of magnetic tape and attached them, like bows, to paper clips (below)

-instant DJ
-you run the bow along the reader at a certain speed (it take some playing around to get the right speed) and you can replay the tape as it was meant to be heard- but you can run it faster or slower as you want, you can also scratch and repeat parts as you want to hear them.

possible ideas are pretty endless- furnishing the reader into a nice little box, with the reader sticking up would be easy- then making a bunch of 'bows' or 'samples' of whatever i want (keeping in mind that, though it would be difficult, i can record whatever i want onto tapes with no difficulty). then i can sample instruments, clips of voices, famous movie quotes, etc. then i can have a set of bows, labeled and marked where the quote starts and potentially become very good at the instrument.

Update: What about a magnetic tape VJ?
Idea riding on the tail of the above project:
>if I can do this with an audio tape, can you do it with a video tape?
-could I mix visual and audio?
-Reid says that a vcr is much more difficult to mess with- not that I don’t believe him- but I got a vcr and im going to find out for myself (the next I get some free hours)
