A thermomagnetic printer of the in-plane magnetization system includes a magnetic recording layer made of Dy.sub.x Co.sub.(1-x) or Dy.sub.y Co.sub.(1-y) and a base layer made of Ti or Ta. Since the described arrangement enables the magnetic recording layer to be formed by the sputtering method or the electron beam evaporation method, and the like, the magnetic recording layer having a uniform thickness and properties in a large area can be formed without difficulties. In addition, by adopting the Ti layer or the Ta layer as the base layer, a reduction in a residual magnetization can be prevented even when the magnetic recording layer is made thicker, thereby increasing a magnetic attraction force.
