(B) Conventional technology In recording on a magneto-optical recording medium, the magnetic recording layer (17) is irradiated with laser light (LB) and heated as shown in FIG.
As a result, the coercive force of the magnetic recording layer is reduced.
The information is erased and written by changing the direction of the magnetization. As the means for applying the external magnetic field, for example, by using a pot-shaped magnetic head (4), the direction of the applied magnetic field can be easily changed according to the direction of the current flowing through the coil of the pot-shaped magnetic head (4). Information can be overwritten on a recording medium. However, when the pot-shaped magnetic head (4) is used, the magnetic flux leaking from the pot-shaped magnetic head (4) causes the magnetic recording layer (1) when heated on the magnetic recording layer (17).
Since the magnetic field Hc needs to be equal to or higher than the magnetic field Hc of 7), the urn-shaped magnetic head (4) needs to be floated as close to the magneto-optical disk (19) as possible. However, in the conventional magneto-optical disk device, the pot-shaped magnetic head (4) does not follow the run-out of the magneto-optical disk (19), and the run-out of the magneto-optical disk (19) is ± 0.5 + a (a is, for example, a margin. 0.1mm). As described above, since the distance between the magneto-optical disk (19) and the pot-shaped magnetic head (4) is large, the magnetic field must be increased.

On the other hand, there is a floating magnetic head as a method for following the surface deflection of the magneto-optical disk (19). The floating principle uses a dynamic pressure generated by the viscosity of air when the magnetic head and the recording medium move relatively at high speed, and maintains a small wedge-shaped gap between the magnetic head and the recording medium. It uses a gas lubricated bearing. FIG. 5 shows a mechanism used in a hard disk drive as an example of a flying magnetic head. FIG. 5 (a) shows the magnetic head (21).
This is a state of the flying slider (3) [hereinafter referred to as a flying slider] provided with a magnetic head provided with a magnetic head. Fifth
FIG. 2B shows an example of a supporting mechanism of the flying magnetic head. The flying slider (3) is pressed by the support spring (23) at several tens to one hundred and several tens mN, and is in contact with the magnetic disk (24).
In this state, when the magnetic disk (24) rotates in the direction (B), an air film floating force is applied to the flying slider (3) by the above-mentioned floating principle, and the magnetic disk (24) floats in proportion to the light load of the support spring (23). The above mechanism makes the flying slider contact the disk with a light load. This is a so-called contact start / stop method. The support spring (23) is attached to the position control arm (1), and the positioning arm (1) controls the position in the track direction.

(C) Problems to be Solved by the Invention In order to reduce the power consumption required for generating a magnetic field, the floating type magnetic head has also been tried for a recording method using a magneto-optical disk. Generally, the generated pressure is proportional to the relative speed to the disk, and in recording using a magneto-optical disk, for example, when the linear speed of the CD standard is 1.2 to 1.4 m / sec, the linear speed of the hard disk is 40 to 60 m / sec. Due to the extremely low speed, the generated pressure is quite low. As a result, the required pressure is not generated, and the magnetic head does not fly.

± 0.5 mm when the runout of the magneto-optical disk conforms to the CD standard
± 0.1mm for conventional hard disks
In the floating method of the hard disk, the pressing force fluctuates greatly due to the expansion and contraction of the pressing spring, and the balance between the spring pressing force and the floating pressure shifts as the surface run-out increases.

Further, when the surface run-out increases, the relative angle between the magneto-optical disk and the flying slider changes due to the inclination of the magneto-optical disk. Therefore, the flying slider has no ability to sufficiently follow the surface run-out fluctuation, and the flying slider and the A small wedge gap with the magnetic disk cannot be maintained. Therefore, the fluctuation of the wedge gap causes the fluctuation of the generated dynamic pressure, and the floating becomes unstable. In the worst case, it becomes impossible to fly, and the flying slider and the magneto-optical disk come into contact.

(D) Means for Solving the Problems In view of the above problems, in the present invention, a seesaw balancer or a rotating mechanism is applied to a connecting portion between a flying slider and a supporting spring in a floating magnetic head supporting mechanism.

(E) Action By using a seesaw balancer to reduce the rotational moment of the flying slider, it is possible to obtain stable magnetic head flying characteristics, and it is also caused by fluctuations in the spring pressing force due to the deflection of the surface of the magneto-optical disk. The effect on the ascent was reduced.

Furthermore, by providing a rotating mechanism at the connection between the flying slider and the support spring, the floating slider is made rotatable, so that the fluctuation of the wedge gap due to the runout of the magneto-optical disk falls within the minimum range in which it can fly. In addition, the fluctuation of the flying height at the time of flying is reduced.

(F) Embodiment The present invention will be described with reference to FIG. A magneto-optical disk (19) as a recording medium includes a disk substrate (16) made of acrylic resin or the like, a magnetic recording layer (17), and a protective film (18). An optical head (15) is arranged above the magneto-optical disk (19). The laser (10) in the optical head (15) continuously oscillates and outputs a DC laser beam (LB) of almost constant intensity, and this laser beam (LB) is bent by the beam splitter (12). Then, the light is condensed by the objective lens (11) near the recording position of the magnetic recording layer (17) of the magneto-optical disk (19), and is subjected to heating for magneto-optical recording. The reflected light (R-LB) from the magneto-optical disk (19), which reads the difference in reflectance of the magnetic recording layer (17), passes through the objective lens (11), the beam splitter (12), and the polarizer (13). The light enters the optical sensor (14) and is provided to focus servo, tracking servo, and magneto-optical signals. On the other hand, a pot-shaped magnetic head (4) is arranged below the magneto-optical disk (19). The urn-type magnetic head (4) is made by winding an exciting coil around a soft magnetic core, and a current modulated according to recording information is supplied to the exciting coil, whereby the exciting coil is supplied according to the recording information. A modulated high frequency magnetic field is generated. By applying a magnetic field to the N pole and the S pole, the laser beam irradiation position is magnetized by the generated magnetic field to perform recording.

Next, a floating type magnetic head supporting mechanism for magnetic field modulation according to an embodiment of the present invention will be described. Position control arm (1)
The seesaw-type balance arm rotatably mounted on the rotary shaft A via a rotation axis A (5) includes a left balance arm (6) and a right balance arm (7). A balance weight (8) is attached to the left balance arm (6), and a flying slider (3) holding a pot-shaped magnetic head (4) is attached to the right balance arm (7).
In the initial state, the flying slider (3) is in contact with the magneto-optical disk (19) with a slight difference in moment between left and right loads. When the magneto-optical disk (19) is rotated in the direction of the arrow in this state, the difference between the left and right rotational moments and the flying force caused by air are balanced, and the flying slider (3) floats.

Next, a description will be given of a magnetic head supporting mechanism for floating magnetic field modulation according to another embodiment of the present invention. As shown in FIG. 2, the tip of the support spring (23) has a U-shape, and each tip is provided with a rotating shaft B (25) for rotatably connecting the flying slider (3). ing. The support spring (23) is configured to press against the magneto-optical disk (19). The center of the rotating shaft (25) of the flying slider (3) is on the support spring (23) side. When the magneto-optical disk (19) rotates,
The flying height is determined by factors such as the speed of the magneto-optical disk (19), the angle of the flying slider (3), and the load on the magneto-optical disk of the support spring (23) and the flying slider (3).
Next, a case in which surface run-out occurs will be described. When the runout occurs and the distance between the magneto-optical disk (19) and the flying slider (3) increases, the dynamic pressure in the wedge gap decreases, and the support spring (23) reduces the wedge gap.
And the flying slider (3) moves. Conversely, when the distance between the magneto-optical disk (19) and the flying slider (3) decreases, the support spring (23) increases the wedge gap.
And the flying slider (3) moves. Even when the relative angle changes as described above, the wedge-shaped gap between the flying slider (3) and the magneto-optical disk (19) is formed by the rotational motion of the flying slider (3) about the rotation axis and the supporting spring ( Compensated and maintained by the fluctuations of 23). The resulting magneto-optical disk (19)
And the flying slider (3) can be kept at substantially the same distance.

FIG. 3 shows a magnetic head supporting mechanism for a floating type magnetic field modulation which is an improved type of another embodiment of the present invention. In the flying slider (3) with a rotating shaft, the connection between the flying slider (3) and the support spring (23) is not completely fixed, but a connection between the shaft and the hole. Therefore, it is conceivable that an unspecified behavior of the flying slider (3) occurs due to minute vibration of the supporting system of the flying slider (3), the magneto-optical disk (19), and the like. When the magneto-optical disk device is placed at a position other than the horizontal position, for example, when it is placed vertically, the center of gravity of the flying slider (3) toward the magneto-optical disk (19) changes, and as a result, the flying slider ( 3) may rotate, and no wedge gap may be formed between the flying slider (3) and the magneto-optical disk (19). In order to prevent this, the pressing piece (27) and the flying slider (3) in the middle of the Y-shaped support spring (23) are so arranged that the flying slider (3) always faces the magneto-optical disk (19). A pressing force is applied by a pressing spring (26) provided therebetween, and a stopper is provided by a light spring load for preventing free rotation of the flying slider (3). As described above, even when the surface of the magneto-optical disk (19) faces in the vertical direction, the distance between the magneto-optical disk (19) and the flying slider (3) can be stably maintained at the same distance.

(G) Effects of the Invention According to the present invention, the flying of the magnetic head can be obtained even at the rotation speed of the CD standard, and the influence of the deflection of the surface of the magneto-optical disk on the flying characteristics is reduced. Fluctuations in the wedge-shaped gap between the disk and the disk are kept to a minimum that allows the disk to float, and contact between the floating slider and the magneto-optical disk due to inability to float and unstable floating are eliminated.
