BG 5. Description of the invention (1) The present invention generally relates to a rotating disk information storage system, and more particularly to a magnetic disk storage system, in which the magnetic converter is arranged on a sliding head to physically contact at the operating speed The storage medium keeps the sliding suction head in contact with the surface of the storage medium by the friction attraction effect. In the magnetic storage system, the storage of an information bit uses a concentrated magnetic field as a small capacity on the disk to correct the magnetic domain to the desired direction in that small capacity. In the optical storage system, an information bit storage is to concentrate a laser beam on a small spot on the disc to heat the medium and then effectively produce a physical change at that point on the medium material. In the case of the magneto-optical storage system, the heat generated by the laser jet causes the correction of the magnetic field supplied by the magnetic domain K at this point. In all mobile disk storage systems, the request to increase the storage capacity is achieved by increasing the bit density of the area on the storage disk. In the disk storage system, the increase of the regional bit density requires the reduction of three basic parameters, the gap length of the disc writing converter (head), the thickness of the magnetic storage medium and the head-to-disk spacing. For a given gap length and media thickness, the smaller the head-to-disk spacing, that is, the lower the head takeoff height, the smaller the achievable cell size. The limitation of low takeoff height is the contact record. Here, the slider is physically in contact with the rotating disk, ie, the slider continuously slides or rubs on the surface of the disk ~ and the read / write converter is as close as possible to the slider Edge-to-disk surface ° US_Patent Case No. 4,819,091 to 8 "62〇〇21? 7 et al., Designated to the immediate trustee 'revelation-magnetic contact recording device which contains a magnetic read / write head set at one 'The sliding head is made of a single crystal material and is in physical contact with the rotating storage medium.

The sliding head is balanced by a sister and suspended above the rotating disk, and the balancing arm includes a plate spring device M to impart rotational force to the sliding head M. This causes the drag portion of the air sleeve bearing surface of the sliding head and the moving magnet Surface contact. A magnetic head placed on or buried in the trailing edge surface of the sliding head has a magnetic head surface M close to but not in contact with the surface of the magnetic sill to prevent wear of the head surface.

Description of invention (έ /) One of the celebration points is that the sliding head can be other than M zero or negative This provides minimum friction on the slider / disk surface interface during load operation Load and minimize the friction of the contact surface between the drive head and the disk. Basically, the mobile disk storage system of the conventional technology S, such as the hard disk 1 uses "moving and stopping in the contact horizontal mode", 丨 · e. When the magnetic is still, the sliding head stops on the surface of the disk. When the disk starts to rotate, such as an air sleeve bearing on the surface of the sliding head and the disk, the sliding head dances on the surface of the disk. When the disk rotates Stop, "the moving head is mounted and pauses on the surface of the magnetic disk. The surface of the magnetic hoist becomes smoother, and the problem of static friction between the moving head and the surface of the magnetic disk occurs as a chess game. This question is clearly shown in the magnetic The disc rotating motor mattress seeks a high starting torque from the bark state on the surface of the magnetic disc to start loosening the sliding head. This problem is aggravated by the fact that the positively applied load on the sliding head needs to resist the upward force generated when the disk rotates. In the mobile disk storage system according to the present invention, the sliding head has a zero or micro-positive applied load which causes the sliding head to stop above the surface of the disk when the disk rotation stops; ie, there is no relative movement between the sliding head and the disk brown . Even, the sliding head is provided on its suspension arm, so that it can be slightly tilted so that a forward or front tip or sloping edge slightly contacts the surface of the disk. The magnitude of the static friction force generated by this point contact is negligible and the disk rotation starts easily. When the rotation starts, once the magnetic disk reaches its speed, * ·.. * The speed of this point of contact makes the frictional charge generated by Fu sent to the bottom of the moving head. When a sufficient charge is generated on the contact surface of the sliding head, the frictional contact force draws the sliding head on the surface of the disk, so that the contact surface of the sliding head is parallel and physically contacts the surface of the disk. As described above, once the disk holder rotates above a critical speed, the slider head is in contact with the surface of the disk f.

Description of the invention (Shi) The detailed description of the better real jiuyun now refer to _1 An information storage system includes at least one hard storage disk 12 fixedly supported on the sleeve H and rotated by a disk drive motor (not shown). The recording medium 11 is placed on the disk to-known The method is in the form of a ring-shaped centralized data track, for example, the storage medium is covered by a protective layer such as carbon or hawaii. At least one sliding head is placed in contact with this protective outer surface and supports one or more disks Reading / writing head. The sliding head 13 is connected to a transmission arm 19 by a hanger 15. The moving arm 19 is embedded in a close mechanical device such as a voice coil motor (not shown) to place the reading / writing head On the required data track. When the storage disk 12 rotates, the slider 13 moves radially across the disk so that the read / write head can advance to different parts of the disk surface 11. According to the present invention, the slider is moved from The suspension arm 15 is placed in 'It is in contact with the recording medium at normal operating speed' and this speed is The moving head 13 and the disk surface 11 are generated by relative movement in the direction indicated by the arrow 16. The sliding head 13 holds the ore directly in direct contact with the disk surface 11 even when the sliding head and the disk surface meet every 20 seconds. The considerable speed of the public " feet, which is the special excitement of the present invention. The gift-giving contact is maintained by an attractive force. As-the frictional attractive force has enough strength to resist the upward force generated by the air calendar. The lifting force is to explain the surface of the disk and move it to force the sliding head to fit away from the surface of the disk. The above referenced US Patent No. 4,819,091 shows that the detailed disk storage system includes-the sliding head physically contacts the storage medium and is completely here. It is proposed to include the cover as a reference. The frictional attraction is due to the Coulomb attraction between the frictional charges due to the relative burial between the slider and the disk surface when the body is in contact. The frictional power is relatively low with respect to the speed of the disk. It is higher than some critical speeds of one meter per second. Please read "Notes on the back side and fill in" first.

5. Description of the invention (’/). When the speed is reduced, the frictional attractive force is no longer sufficient at a certain point to maintain the contact between the slider and the disk surface. This release point becomes a function of disk wear and rough surface. In addition, when the suspension arm is loaded, i.e. the external load is reduced to a negative load on the sliding head 13, and the restoring force is generated. That is, when the two surfaces are separated by a strong force, the frictional attractive force increases and the resistance to force the two surfaces to separate is resisted. The restoring force keeps the sliding head 13 in stable contact with the disk surface 11 although the surface of the disk 12: rough and worn. As shown in Figure 12, when the external load is positive * the actual load on the slider, ie the frictional force measured between the slider and the disk surface is linearly proportional to the external load on the slider 13 and has an additional Contact friction attraction. The net load on the slider-disk surface is the sum of these two forces. When the external load is reduced to the negative area, i.e. the slider is pulled up, away from the disk surface, the net load is reduced, which is the difference between the frictional attraction and the force of pulling the slider. As depicted in curve 14 of Figure 2, when the external load decreases to the negative region, the friction-to-load characteristics gradually deviate from the linear cutoff seen from higher loads in the positive load region. As the negative external load I on the slider increases, the net load on the slider disk interface slowly reduces friction as well. The frictional attraction force is a weak function of the speed of the magnetic tunnel, which is above a minimum valve speed. The restoring force effect and the small floating load increase the stability of the sliding head and the extreme surface of the sliding head-disk of the contact recording system, „f. * T Low wear, and this _ contact recording system uses the phenomenon of friction attraction. The sliding head and The frictional attractive force generated by the relative motion between the contact surfaces of the magnetic disk contains a restoring force, like a spring restoring force, with an increasing frictional attractive force against any force that wants to separate the sliding head from the disc surface. When there is any interference When power is supplied, it causes the sliding head to be separated from the disk.> For the response, please first read "Notes on the back and then fill in the j.

When there is no restoring force effect, the wear of the disk surface will make the sliding head fully separated to make the disk contact the surface of the disk The moving air layer is completely raised from the disk by the sliding head. The result is that a large positive force is required to be supplied to the sliding head to resist the air bearing lifting and any dry force is negligible. In addition, since friction attracts recovery It is only enough to resist interference, no additional load appears on the sliding head / disk contact surface .: In this way, the system can operate with little or no external load on the sliding head. The best system performance can achieve κ basically zero Or a slight negative load on the slider when the disk is rotating. In addition to the physical properties of the material • The extremely low load on the driving head is one. In order to minimize the wear of the contact surface of the slider and the disk and reduce the adhesion effect Important factors. The geometry and smooth surface of the sliding head also play an important role in minimizing wear. When the frictional attraction generated is sufficient to resist the upward lift caused by the air sleeve bearing • Make the air sleeve bearing effect itself practical It is also important to minimize the ground. However, since the air sleeve bearing does provide a favorable lubricating effect, it is undesirable to complete the removal of the air sleeve bearing.

For the understanding of the friction charging phenomenon, the prediction and the recovery force effect exert friction to attract contact » It is difficult to match the behavior of the material. The usual rule is that when the friction of the material versus the load curve, the slider and the disk have a characteristic form, especially in the negative load area, similar to the curve shown in _2 14 ， This material shows the behavior of friction attracting contact and sliding. In the negative load area, the characteristic "The direction of the system leads to an extended monotonous reduction of the friction against the negative load indicates a strong recovery force. -10- Please read the back first Precautions for refilling> page • playing · A 4 (210X297 characters)

A6 B6 V. Description of the invention (I 〇) As shown in Table I, the 'broken peripanic substances are potentially effective in frictional contact. The path for the outflow of triboelectric charge needs to be provided. It is important that the resistance of the disk track is not 5: However, for general requirements, most of the friction charge generated should be dissipated to the ground on a separate disk. Within the required time. Mainly, the magnetic media used in thin-layer disks are metallic and if grounded, the outer layer is kept thin enough to eliminate the charge. If the magnetic medium is non-conductive, as in some examples where oxygen is commonly used, careful design for the outflow of triboelectric charge is essential. When the disk Runji will reduce friction and enhance the wearability of the disk and the slider, the slip agent and other contaminants that can be absorbed will affect the triboelectricity and friction performance. On the S side, the presence of lubricants in the form of polyhexalipid did not show a toxic effect on the contact friction phenomenon: The phenomenon refers to FIG. 3, which shows a disk storage system in accordance with the principles of the present invention.

Ho V. Description of the Invention (11) (VCM) 27, for example. VCM is a coil that can move in a fixed magnetic field: the direction and speed of coil movement are controlled by an applied current signal. When the disk 12 rotates, the slider 13 moves radially across the inside and outside of the disk so that the head 21 can advance to a different position on the surface of the magnet containing the stored data. Various components of the disk storage system are controlled by the operation of the signals generated by the control unit 29, such as the forward control signal and the internal clock signal, which include the logic control circuit, the storage device, and a microprocessor. The control unit 29 generates a control signal M to control a number of operations, such as the motor control signal on line 23 and the head position control signal on line 28. The control signal on line 28 provides the desired shifting wheel gallery K to optimally move and place a selected slide head 13 onto the desired data track on the associated disk 12. The read and write signals are communicated and come from the let / write head 17 through the recording channel 25. The above description of a disk storage system and related descriptions are shown in FIG. 3 for the purpose of M description only. Such a storage system can contain a large number of storage disks and VCMs, and it is obvious that each starting arm can support a large number of sliding heads. The contact recording disk storage system of the present invention is fully operable with any such removable storage device, where the sliding head contacts the storage medium at the operating speed. — Referring now to FIGS. 4 and 5, according to the principles of the present invention, the slider 13 is connected to a suspension arm and placed so that when the disk 12 is stabilized or stopped * the slider 13 suspends contact with the disk surface 20.

For a preferred real drag example, the tilt angle in the range of 1.5-5.0 degrees is sufficient. When the disk rotation starts too large The tilt angle may cause the tip 31 of the slider to dig in the surface of the disk. The magnitude of the static friction force generated by this slight contact is negligible and the disk rotation can be easily started. Rotation starts and the disk 12 reaches its operating speed, the contact at the top 31 of the edge: adhesion causes frictional charge, and this charge is spread on the bottom or contact surface of the sliding head 13. When the charge generated at the top 31 of the edge starts to spread • The moving head 31 is gradually attracted to the disk surface 20. Due to the increased contact area, this encounter strengthens the generation of triboelectric charge and At a certain point, the full charge stack causes the slider to be suddenly attracted and pulled to the disk, so that the contact surface of the slider is parallel and the surface of the slider contacts the surface of the disk 20. Once the disk continues to rotate at a sufficient speed | The sliding head maintains sliding contact with the disk at a zero or slightly negative external load. When the disk rotation stops * the sliding head 13 is lifted and tilted to its rest position with the edge tip 31 contacting the disk surface 20 at its original angle The sliding is illustrated graphically in the self-loading process at _5 as a function of time. The disk rotation starts at the left of the graph at time zero. When the disk rotation speed increases * Friction increases when the load remains relatively fixed The friction of the friction and the magnitude of the load is due to the repetitive wear of the disk and the gradual acceleration of the disk.

In a preferred embodiment, a single crystal sapphire slider and a 3.5-hour particle disk are rubbed. peak The signal 34 corresponds to approximately 2400 rpm and the final rotation speed in a unitary system is • 14- Please read “Notes on the back side first” and then install it • Green • A4 (210X29 * 7 male (Read) A6 Βυ__ printed by the Central Standards Consumer Labor Cooperative of the Ministry of Economic Affairs. 5. Description of the invention (5) 3600 rpm. After the high friction spike signal, when the sliding head starts to contact the disk surface 20, the friction curve drops by almost a value. It is equal to the lower value of the load. Relatively, the 'load curve follows its oscillation action. This is most likely due to the contact' slippage occurring in the non-linear area of the friction vs. load curve, where the sugar difference relative to the load is small. In referring to FIGS. 6-8, according to the present invention, the slider 13 is placed so that it is in sliding contact with the recording medium U, when the disk is produced at a normal operating speed by relative burial at a predetermined rate, at The direction indicated by arrow 32 is between the slider 13 and the disk surface 20. A "Snow Pi〇w" (snow Pi〇w) or, "boat-like" sliding head geometry is used to refract surface particles, thus minimizing dust and other pollution from the surface of the sliding head and disk. In a preferred embodiment, the sliding head 13 is formed in the shape of an isosceles triangle and has a vertex or top edge tip 31 along a relative buried line (as indicated by the arrow 32), which may be 36 00 rpm or Bigger. The bottom edge or contact surface of the sliding head is flat and overlaps at least one flat surface.
