ABSTRACT:
An information recording medium, an information recording/reproduction head, and an information storage device are provided for performing a track servo operation at a smaller track pitch than that conventionally used without reducing the widths of servo burst patterns. The widths of servo burst patterns (107, 108, 109, 110) are increased over a track pitch (TP) and the end of the servo burst pattern is disposed so as not to coincide with a center line (111) of an information track. In addition, a servo magnetic head (112) and a reproduction magnetic head (113) are implemented in one magnetoresistance element (159).
