Title:
組み込まれた電源を備えたディスク記録担体上のチップ
Document Type and Number:
Japanese Patent JP4313305
Kind Code:
B2
Abstract:
A system for rendering information from a record carrier is described. The record carrier ( 1 ) has an integrated circuit ( 4 ) build in. The chip communicates contactlessly with the device. Power for the chip ( 4 ) is generated from low frequency magnetic flux changes by a power supply coil integrated on the chip. The device has a read head ( 22 ) and a magnetic array ( 21 ) having a plurality of poles for generating a static magnetic field having areas with positive and negative magnetic flux for cooperating with the power supply coil, and drive means ( 26 ) for rotating the record carrier for scanning the track via the head ( 22 ) and for moving the integrated circuit ( 4 ) through the magnetic field for creating the low frequency magnetic flux changes.
