Abstract: A digital media transaction kiosk and method which provide security for digital media. An example kiosk includes a digital media identifier for reading an identifier of a digital media item on a representative of the digital media item provided by the customer, and a digital media dispenser for dispensing the digital media item to the customer using the identifier.

Abstract: A bar code scanner has a housing including a surface having a transparent scanning window. The housing contains optical components including a spinner and pattern mirrors arranged to produce sets of scan lines. The spinner is operable at two, substantially constant, non-zero spin speeds.

Abstract: A timing and mirror position detector for use in a bar code scanner having a rotating optical assembly. The optical assembly is rotated by a motor which produces a fixed number of pulses per rotation, at least one of the pulses occurring each time the motor passes through a reference position as it rotates. The pulses are continuously monitored and counted. Elapsed time from the time a reference pulse occurs is accurately measured and correlated by a processor with events of interest. When an event of interest, such as a bar code scan, occurs, the timing and pulse count are evaluated and processed to determine the angle of rotation of the motor at the time the scan occurred.
