Ocean Bottom Vector Magnetometer (2)

-Design and Test of The Bubble Memory Recording System?-

Abstract

"Bubble memory recording system" for the new model of magnetometer is des cribed.Magnetic bubble memory has several characteristics, e.g., small in size, low power consumption and so on, required for recording system used at the ocean bottom.One board micro computer based on the Z-80A CPU is used for control of the magnetic bubble memory.Every 2.5 minutes' observation of the geomagnetic field at the ocean bottom for more than two months will be possible using the magnetic bubble memory system.
