Title:
CIRCUIT DEVICE WHICH SELECTS ONE OF MULTIPLE MAGNETIC SYSTEMS IN MULTIPLE MAGNETIX HEAD AND CONNECTS IT WITH READING CHANNEL OF MAGNETIC LAYER MEMORY UNIT.
Document Type and Number:
Japanese Patent JPH0573809
Kind Code:
A
Abstract:
PURPOSE: To make a circuit device reliably operate a selective connection of a signal read out of a selected magnetic system to a read channel of a magnetic layer, throughtransmission, by eliminating noise as low as possible by a simple means.
CONSTITUTION: A pre-amplifier is assigned to each magnetic system of multiple magnetic heads. This pre-amplifier has an input stage 41 and a final stage 42. The multiple magnetic head is spatially and directly provided with the input stage 41, and is spatially connected with the final stage assigned to a read-out channel. 7 via a flexible connection line 80.
