Abstract
An electric field read/write head, a method of manufacturing the electric field read/write head, and an information storage device including the electric field read/write head are provided. The electric field read/write head includes: a substrate having a first surface facing a recording medium and a second surface that is perpendicular to the first surface; and a protrusion formed on the second surface and having at least a portion facing the recording medium, wherein a resistance sensor comprising a source, a drain, and a channel is included in the protrusion. An insulating layer and electric field shield layers are further sequentially formed on opposite sides of the protrusion, respectively, and at least one of the electric field shield layers is a write electrode.
