Above is a photo from my sonic journal.

NOTES: Sound on Sound looping is a technique that can be used on a cheap/expensive tape recorders. This is done by extending the signals on the tape so it creates a loop or delay effect.

1. On a tape deck you have 3 heads; the erase head, write head and read head. The signals being put onto tape run past all three of these heads.
2. The erase head erases the signal as it passes.
3. If you remove the erase head the signals will continue and record over each other. NOTE: Expensive tape recorders and machines usually allow you to remove the individual heads as they are much bigger. With cheaper tape recorders you have to be a bit more creative.
4. Using a thin bit of tinfoil you can cover the ‘erase’ head so the tape can’t touch the erase head.
