A light induction type thin film magnetic recording head according to the present invention includes a lower magnetic core (2) formed on a substrate, an upper magnetic core (6) whose front end part is connected to the lower magnetic core through a magnetic gap film and whose rear end part is directly connected to the lower magnetic core with a back contact part (11) formed of a magnetic substance, and an insulating layer (3) formed between the upper magnetic core and the lower magnetic core, characterized in that an optically transparent waveguide part (5) whose width is smaller than the width of the upper magnetic core and whose thickness is thinner than the thickness of the upper magnetic core is buried in the upper magnetic core, and a coil (8) which generates magnetic flux in a magnetic circuit composed of the upper magnetic core, lower magnetic core, magnetic gap, and back contact part is arranged around the back contact part.
