ABSTRACT:
A solid state music player for reproducing and playing stored digital information from a magnetic bubble-memory device, which has a magnetic bubble-memory module for receiving the bubble-memory device which contains the stored program. There is also a function-timing generator, which is coupled to the magnetic bubble-memory module for generating control and timing signals for the module. A microprocessor is connected to a bubble-memory controller which in turn is coupled to the function-timing generator, and the bubble-memory controller responds to commands from the microprocessor to send control signals to the function-timing generator, necessary to access the digital data stored in the bubble-memory device. A digital-to-analog converter is coupled to the microprocessor for converting the digital stream of information from the microprocessor into analog signals, which then can be played through loudspeakers or on a video screen to reproduce the stored digital information from the bubble-memory device. In this manner, large amounts of stored information, such as musical programs or videotape programs, can be stored on a small bubble-memory chip and reproduced as desired.
