Low Res Optical Encoders for Speed Control

This is the sort of workaround I'm interested in if we can't do it with a 360 count disc. The only thing that would usually concern me about this approach is a layer of tape (which if I remember correctly is thicker than the plastic disc) could change the tolerance on the encoder for the distance from the sensor to the disc. Was this even an issue, or could it be easily resolved if it does present a problem?
