Abstract
A multichannel magnetic head utilizing the magnetoresistive effect comprises a plurality of magnetoresistive effect type reproducing magnetic head elements arrayed between a first and second magnetic shield and electrodes wherein the reproducing magnetic head elements are arrayed in parallel on at least the first magnetic shield and electrode. Electrodes on one side are constructed commonly by the first magnetic shield and led out as a single common terminal decreasing the number of terminals. Therefore, the number of the terminals in the multichannel magnetic head using the magnetoresistive effect can be decreased, the multichannel magnetic head can be miniaturized, the occurrence of a short-circuit between the terminals or between the leads can be removed, the occurrence of fluctuations of element characteristics can be removed, the multichannel magnetic head using the magnetoresistive effect can become highly reliable and a yield of the multichannel magnetic head using the magnetoresistive effect can be improved.
