極めて曳好なもの、となる。FIG. 1 is a cross-sectional view of a magnetic head showing an embodiment of the present invention, in which a core made of a soft magnetic material such as ferrite, Sendust, etc. is used to record and reproduce magnetic fields. A coil 4, a coil frame 5 that holds the coil, and a pair of Nuriders A and Nurider B (numbers 2 and 53 in the figure) that guide and hold the core by the side surfaces.It is composed of a holding member 8 that holds these. This is the lubricating layer that is the key point of the present invention, and in Figure 1, the core and slider po
is formed between. This lubricating layer can be formed, for example, by sputtering carbon or the like. When the recording medium and the magnetic head come into sliding contact, a lubricating layer such as carbon oozes out onto the contact surface, reducing the coefficient of friction and stabilizing the contact state. Therefore the contact between the media magnetic head! 11! is extremely attractive.

的に安定した潤滑層を形成することが可能である。Figure s5 shows a further embodiment of the present invention, which is the cause of the oblique view of the magnetic head.In this embodiment, a lubricant layer is formed discretely between the tit, slider and core. With this configuration, it is possible to form a lubricating layer without impairing the adhesive strength f between the slider and the core. As can be said, if the lubricating layer is made of carbon, slider A made of calcium titanate,
Chromium II is not suitable for P.
It is possible to form a more stable lubricating layer by rubbing the carbon layer through the ivy layer.
