摘要： PROBLEM TO BE SOLVED: To provide uniform element shapes by installing a sub-mask pattern in the outer periphery of a main mask pattern and spaced therefrom to prevent the spraying-back of a spraying medium. SOLUTION: In addition to a main mask pattern 2, a sub-mask pattern 8 is provided to prevent spraying. This sub-mask pattern 8 is arranged in the outer periphery of the main mask pattern 2 and spaced therefrom. Gaps Da between the main mask pattern 2 and the sub-mask pattern 8 are preferably be set substantially equal to one another in any places. Also, when the main mask pattern 2 includes a slit opening 3 inside, a width Db thereof and the gap Da are set substantially equal to each other. Thus, the spraying-back of a spraying medium can be prevented. Further, since the machined state of the element outer shape surface 7a of an element 7 becomes substantially similar to that of the element inner shape surface 7b thereof, uniform machining is performed.

CONSTITUTION:The magnetic head is provided with the head core and the winding wire of the head core in the slider main body 2, and the slider main body 2 is connected to a magnetic head driving device by a member having the elasticity of a flexure and a gimbals, etc. The sliding surfaces 21, 22 are provided on the recording opposite surfaces of the slider main body, and the magnetic field generation part 3 in the head core is provided between them. A part of a spherical surface is present on the sliding surfaces 21, 22 respectively, and they are in point-contact with the surface of a recording medium respectively.

摘要： PROBLEM TO BE SOLVED: To obtain the device, in which an azimuth angle control is properly conducted even though a positioning mechanism is a rocking type, by angularly rotating a floating head slider against a load beam, adjusting the skew angle of the magnetic head, setting and controlling the azimuth angle and conducting an azimuth recording on a magnetic disk medium.
SOLUTION: A relatively large voltage is applied to a piggyback actuator, a floating head slider 20 is angularly rotated against the load beam, the skew angle of a magnetic head 20a is adjusted, the azimuth angle is set and controlled and a recording is conducted by alternatively varying the polarity of the azimuth angle among adjacent tracks. The slider 20 maintains a skew angle + β by the rotational control of the actuator and an information recording is conducted. Thus, the recorded pattern recorded on a track N has an azimuth angle + α, wherein α=β.
