Abstract
A read head for perpendicular magnetic recording that reduces side reading. The read head includes a read element and a magnetic shield spaced apart from the read element. The magnetic shield at least partially surrounds the read element at an air-bearing surface of the read element. The ratio of an air-bearing surface area of the magnetic shield to an air-bearing surface area of the read element is from about 1:1 to about 40:1.
