Which sensor is used with an encoder disk?
A slotted optical sensor (photo interrupter) is used. As the disk turns, the holes let light pass and block it, producing pulses that a microcontroller can count to find speed.
How can I detect the direction of rotation?
Use two optical sensors placed at slightly offset positions around the disk. The order in which their pulses change shows the direction, which is the usual quadrature method.
