A washing/drying method utilizing sonication, comprising: dipping a material to be washed into an aqueous solution containing a surfactant having a water repellency so that at least one molecular layer of the water repellent surfactant is attached to the surface of the material to be washed; applying sonication to the aqueous solution; and then drying the material according to a known drying method such as vacuum drying, shaking off, blowing with gas and heating; or heating the material to be washed with steam at a temperature of less than 100.degree. C. in an atmosphere reduced to a pressure such that the boiling point of water becomes less than 100.degree. C.; and then drying the material according to a known drying method such as vacuum drying, shaking off, blowing with air, and heating.

Washing/drying method utilizing sonication

A mounting portion (protruding portion provided with a through hole) of a magnetic head assembly is fitted into an insertion hole formed at the forward end of a carriage arm, and a thus-produced inlay portion is disposed between adjacent first members having a V-shaped slit. A second member is pushed into the V-shaped slit of each first member and the magnetic head assembly is pressed against the carriage arm by the expanding force of the slit portions of each first member which is produced in proportion to the amount of insertion of the second member, and the magnetic head assembly is held in a fixed state. In this state, a caulking ball is press-fitted into the through hole of the protruding portion with a caulking pin so as to caulk the inlay portion. The magnetic head assembly is pressed against the carriage arm perpendicularly thereto.
