摘要： PURPOSE:To enable stable recording and reproducing and to improve the durability of a magnetic disk by providing a means to suppress the surface oscillation of the magnetic disk in a hard case. CONSTITUTION:In the internal part of a hard case 3 in a cartridge 1, a stabilizing member 7 is arranged on the same reference surface as a magnetic disk 2. The surface of this stabilizing member 7 is formed to be a smooth surface or a soft material such as nonwoven fabric, etc., is attached to the surface. Then, even when the surface of the stabilizing member hits the disk 2, the disk is not damaged. Thus, the vibration of the disk 2, which is generated by pressure fluctuation in the flowing-out end of a negative pressure slider 5 and deformation caused by the negative pressure of the disk 2, can be suppressed. Accordingly, contact between the magnetic disk and a magnetic head is made stable and the reliability and wear resistance of recording and reproducing can be improved.

摘要： PURPOSE:To stably record information and to improve the durability of a magnetic disk by providing a specific groove part on the magnetic disk. CONSTITUTION:A magnetic core 7 of one magnetic head 2 or 3 is made to face a groove 11 of the other magnetic heads 3 or 2, and the magnetic core is brought into contact with a magnetic disk 1 by means of suitable press- contacting force by using the flexibility of the magnetic disk 1. Further on each second foot parts 12 of the first or second magnetic head 2 or 3 arranged on external or internal peripheral side of the magnetic disk 1, a negative pressure generating groove 13, which is made deeper from the upstream side in the rotation direction of the magnetic disk 1 toward the downstream side, is formed, when the disk 1 is rotated at high speed, the negative pressure is generated by the fluid force between the negative pressure generating groove 13 and the disk 1, and force to attract the disk 1 is operated. Consequently the vibration of the disk 1 generated by the high-speed rotation is absorbed, the magnetic heads 2 and 3 come in contact with the disk 1 at constant surface pressure, stable recording/reproducing is attained, and further the durability of the disk 1 is improved.

摘要： PURPOSE:To suppress the face wobbling of a disk and to improve the durability of the disk by providing a step shape projection and a rail shape guide at the internal plane of a case. CONSTITUTION:The step shape projections 10 are provided at upper and lower cases 3 and 4 in the neighborhood of a side to which the disk from a head insertion hole 6 flows in. Also, the rail shape guides 9 and 11 are provided in concentrically circular arc shape at the insides of the upper and lower cases 3 and 4 that are an outer peripheral part and an inner peripheral part outside the recording and reproducing plane of the disk 1 at the side to which the disk flows in from the projection 10. An air current when the disk 1 is rotated in such constitution is collected with the guides 9 and 11, and high air pressure can be obtained at the projection 10, which functions so as to support the disk 1 at the rotary space of the cases 3 and 4. In such a way, the face wobbling of the disk 1 can be suppressed with a fluid force, and the durability of the disk can be improved.

摘要： PURPOSE:To regulate the face wobbling of a disk and to improve durability by forming a liner on one side confronting with the recording plane of the disk with a member whose surface is coarse and the liner on other side with a member whose surface is fine. CONSTITUTION:The member of the liner 5 whose surface is coarse is used in the liner at an upper case 3 side, and the member of the liner 6 whose surface is fine is used in the liner at a lower case 4 side. When the disk 1 is rotated at high speed, an air film is generated between the plane of the liner 6 and the disk 1, and the disk 1 is rotated along the surface of the liner 6. Meanwhile, at the liner 5 side, no air film due to the rotation of the disk 1 is generated, however, a force is applied so as to apply regulation against wobbling in the outward direction of the plane of the disk 1. Also, the disk 1 is brought into contact with the liners 5 and 6 lightly, and dust can be eliminated. In such a way, the disk 1 can be stably rotated without generating the face wobbling, which improves the durability.

摘要： PURPOSE:To enable the stable contact between a disk and a head even in case of a plane wobble by providing a projecting part consisting of a groove along a reversely tapered groove and a rail-like flat part to the outer side of a flat part on a magnetic core side of a magnetic head. CONSTITUTION:The projecting parts having the grooves 11a and 11b and the rail-like flat surfaces 12a and 12b are provided on the outer sides of the magnetic cores 9a and 9b of upper and lower sliders 4a and 4b. Since positive pressure is generated on the flat surfaces 12a and 12b by rotating a disk 1, the disk 1 is bent in the opposite direction to the surfaces 12a and 12b respectively, so that the magnetic cores 9a and 9b come into contact stronger than ever with the disk 1. The disk 1 is prevented from flawing due to extremely bending around at corners of flat surfaces 5a and 5b opposite to this with positive pressure of the surfaces 12a and 12b by the grooves 11a and 11b. By this method, the plane wobble caused by a disk waviness is suppressed to substantially eliminate the wobble in the vicinity of the magnetic cores, thus obtaining the stable contact.

摘要： PROBLEM TO BE SOLVED: To improve the dynamic characteristics of floating and to enable inexpensive mass production with high accuracy by constituting a slider of three partions of an inflow side part, an outflow side part and a coupling part of the total width of gas bearing rail surfaces narrower than these parts. SOLUTION: The gas bearing rails 3 are arranged along the flow direction of gas on both sides on the floating surface of a slider body 1 and are mounted with transducers 2 for recording and reproducing at the outflow ends. The slider main body 1 is formed of straight lines at the outer boundary and consists of three portions; the inflow side part A, the outflow side part B and the coupling part C. Rail cut parts are formed at the coupling part C and the rail width W3 of the coupling part C is formed narrower than the width W1 of the inflow side part A and the width W2 of the outflow side part B. Between a pair of the gas bearing rails 3 is provided a bleed part 5 of a depth d1 having a boundary therewith. The value of the depth D1 is set at about 10 to 20 μm, by which the working of a floating surface shape by non-machining, such as sputter etching, is made possible.

摘要： PROBLEM TO BE SOLVED: To obtain a slider having few float dispersion by combining an inlet part and outlet part in the same surface and providing with a combining part wherein the spread width of a gas bearing rail surface is narrower than the inlet part and outlet part. SOLUTION: Bitten part are formed in the combining part C, and the rail width W3 of the combining part C is formed narrower than the width W1 of the inlet side part A and the width W2 of the outlet side part B. As the gas entered the gas bearing rail 3 moves from the tilted surface part 31 being a pressure rising means to a flat surface 32, it is rapidly compressed and reached the combining part C, and a large pressure is produced in the side part A. Since the spread width of the rail surface is narrow in the combining part 3, one part of the gas is directly made to flow outside the rail 3. Also, although the residual gas advancing through the combining part C is successively compressed, it easily made to flow out in the rail width direction because of the narrow rail width. As the result of it, the bad affect due to the compressibility of the gas is prevented, the damping characteristic is improved, the suitable pressure is produced in the combining part, next the gas is compressed in the outlet side part to produce a large pressure.
