Solid state music player using signals from a bubble-memory storage device
First Claim
1. A solid state music player for reproducing and playing stored digital information from a magnetic bubble-memory device having exposed terminals, comprising:
- a bubble-memory module for receiving the bubble-memory device, which contains the stored program;
a function-timing generator, which is coupled to said bubble-memory module for generating control and timing signals for said module;
a bubble-memory controller coupled to said function-timing generator and said bubble-memory module;
a microprocessor coupled to said bubble-memory controller the bubble-memory controller responding to commands from the microprocessor, to send control signals to the function-timing generator, necessary to access the digital data stored in the module, and reading stored digital information from said bubble-memory module, the controller performing a serial-to-parallel conversion of the stored data as the data is transmitted from said module to said microprocessor;
a digital-to-analog converter coupled to said microprocessor for converting the stream of digital information from the microprocessor into the analog signals;
amplifier means coupled to said converter for amplifying the converted analog signals;
a housing having a plurality of receptacles disposed in its top surface; and
a plurality of electrical contacts coupled to said bubble-memory module and disposed in each of said receptacles along its peripheral walls, for contact with corresponding terminals on the bubble-memory device.

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.
