Abstract:
1. A read head for reading data from a magnetic media having a plurality of adjacent circular tracks, comprising: a bottom magnetic shield layer; a top magnetic shield layer; a read sensor including electrically conducting material disposed between the bottom and top magnetic shield layers configured for sensing changes in magnetic properties of a track on the magnetic media positioned under the read sensor; a side shield assembly positioned between the bottom and top magnetic shield layers and adjacent to the read sensor, the side shield assembly adapted to magnetically shield the read sensor from reading magnetic signals of a track adjacent to the track under the read sensor, wherein the side shield assembly includes a first side shield element that is positioned adjacent to a first side of the read sensor and that extends away from the bottom magnetic shield layer toward the top magnetic shield layer for a shielding distance and wherein the side shield assembly further includes a second side shield element that is positioned adjacent to a second side of the read sensor and that extends away from the bottom magnetic shield layer toward the top magnetic shield layer for a distance about equal to the shielding distance; a bottom electrical contact layer deposited over the first and second side shield elements and the bottom magnetic shield layer; a pair of read gap elements positioned on the bottom electrical contact layer adjacent to the first and second sides of the read sensor, and a top electrical contact layer positioned over the read gap elements and the read sensor.
