Claims

[Scope of utility model registration request]

An iron core having a microgap located close to a magnetic record carrier and configured to constitute a magnetic circuit including the magnetic record carrier is provided, and information is recorded or reproduced from the magnetic record carrier. In a magnetic head, a slider made of a magnetic material, an element such as an iron core configured to configure a magnetic circuit including a magnetic recording carrier, and a shield to prevent the magnetic circuit including the slider and the element from being configured. What is claimed is: 1. A magnetic head, characterized in that the element is superimposed on the end face of the slider with the shield interposed therebetween.
