Bubble Data Recorder for deep space mission

This paper describes the overview of the Bubble Data Recorder (BDR) using magnetic bubble memory developed to install in a deep-space probe Planet-A. The Planet-A is the first Japanese deep space probe which will be launched in 1985 for the purpose of observing Halley's comet by the Institute of Space and Astronautical Science (ISAS). The imaging data of Halley's comet will be recorded by the 1 Mbit BDR along with other telemetry data and reproduced upon command from the earth. For the deep space mission such as the Planet-A, high reliability, small size and low power consumption are required. The BDR developed at this time satisfies these system demands.
