In the figure, reference numerals 1 and 1 denote base frames facing each other at a required interval, and two guide shafts 2 and 3 and a screw shaft 4 are supported between the base frames 1 and 1. A magnetic head 5 is attached to these shafts 2, 3, and 4.
Is supported slidably. The screw shaft 4 is rotated via a drive path of a motor 7, a pulley 8, a belt 9, and a pulley 10, whereby the magnetic head support 6 runs in the axial direction (data writing direction). . Reference numeral 11 denotes a magnetic passbook provided with a magnetic stripe 11a which is in sliding contact with the magnetic head 5. And, on the surface of the screw shaft 4,
Nickel (Ni) -phosphorus (P) plating is applied, and an organic lubricating film is formed thereon.

Form a coating. For this treatment liquid, a lubricant in which the concentration of a mixture of an aliphatic amine compound, dimethyl silicon and water is adjusted to 20 to 50 g / l is used. Further, at the time of coating treatment, the treatment liquid is kept at 30 to 50 ° C.
The shaft is heated in this processing solution.
For 30-60 seconds. At this time, it is desirable that the shaft 4 be swung in the processing liquid.

させることができた。The screw shaft 4 obtained by the lubricating coating process described above has sliding characteristics as compared with the case where the magnetic head support 6 is slid in contact with a conventional electroless Ni-P plating process. Improved, and the shaft slidability was stabilized. As a result, the movement of the magnetic head 5 becomes smooth,
The variation in jitter, which is an important characteristic of the magnetic recording medium reader, was reduced from ± 10% to ± 8% from the conventional value.

タルコストの低減が図れる。Since the organic lubricating film formed on the screw shaft 4 is a very thin film, there is little variation in the film thickness, and the shaft is leveled by electroless Ni-P plating. There is an advantage that the surface state is maintained. In addition, by performing the organic coating treatment, the screw shaft 4 which had a poor finished plating surface roughness and could not be used conventionally can be reused and the total cost can be reduced.

させることができた。As described above, according to the present invention, in a magnetic recording medium reader, an organic lubricant is used to lubricate a screw shaft for slidingly moving a magnetic head support or a magnetic head support . By applying the coating, the following effects can be obtained. (1) Nickel-phosphorous plating or nickel-plating on the screw shaft for feeding the magnetic head or the magnetic head support
After the boron plating treatment, an organic lubricating film treatment is performed, so that the dome-shaped portion due to plating remains as a protrusion.
And stable high slidability is obtained. (2) Nickel-phosphorus plating or nickel-
In the process of boron plating, slidability becomes poor surface roughness is deteriorated due to the occurrence of protrusions, originally defective screw shaft, by performing the organic lubricating coating process, the reuse becomes possible The protrusions may be shaved and become wear powder.
