摘要： PURPOSE:To prevent a magnetic head from being damaged by adsorbing a core slider onto the surface of a recording medium by displacing a negative pressure slider to be set at a second stable position, where force operated onto the negative pressure slider can be balanced with restoring force by positive pressure and negative pressure, when the rotating speed of the recording medium reaches the normal rotating speed. CONSTITUTION:When the rotation of the recording medium is stopped, the negative pressure slider is held at the first stable position (away from the surface of the recording medium by 100mum, for example) sufficiently separated from the recording medium surface where the positive pressure and the negative pressure is not operated. When the rotation of the recording medium is started, a signal is transmitted at suitable timing to impress a voltage to a piezoelectric element 22, and the surface of the piezoelectric element 22 on the recording medium side is displaced to be close to the recording medium surface. With this displacement, a spring arm 26 is elastically deformed, and the negative pressure slider 4 is displaced from the first stable position to the second stable position (away from the recording medium surface by 0.1mum, for example). When the negative pressure slider 4 is displaced to the second stable position, at this second stable position, the positive pressure and the negative pressure is operated onto the negative pressure slider 4, and the force composed of this negative and positive pressure is balanced with the elastic force (restoring force) of the spring arm 26.

摘要： PURPOSE:To realize the magnetic disk device of high reliability at low cost by dividing an integral carriaage into two parts. CONSTITUTION:In the integral carriage, arms parts 2a-2d..., which are arranged in one line, are divided into a first carriage body 1a and a second carriage body 1b every other step. Accordingly, in the first carriage body 1a, an interval between the arm part 2a and arm part 2c... is made double. On the other hand, even in the second carriage body 1b, an interval between the arm part 2b and arm part 2d... is made double. As a result, when a magnetic head assembling body is fitted to the first and second carriage bodies 1a and 1b and afterwards, the first and second carriage bodies 1a and 1b are linked, a space for work to fit the magnetic head assembling body is enlarged to be double and the operability of the fitting work is widely improved. Thus, the magnetic disk device of the high reliability can be realized at low cost.

摘要： PURPOSE:To prevent dust or head crash due to sliding occurring by deviating a core slider to a magnetic recording medium plane side by utilizing wind pressure generated at the time of rotating a magnetic recording medium, and retracting the core slider from the medium plane by floating in a state where the wind pressure is not generated and the core slider is not deviated to the medium plane side. CONSTITUTION:A spring arm 6 is deviated by blowing the wind pressure generated at the time of performing the constant rotation of the magnetic recording medium 1 toward a wind receiving means 11, and the recording and reproduction of information on the plane of a magnetic recording medium 1 can be performed by making the core slider 3 approach the magnetic recording medium 1 side. In a state where the magnetic recording medium 1 is rotated before the constant rotation or it is stopped, on wind pressure to deviate the spring arm 6 to the magnetic recording medium 1 side occurs, therefore, the core slider 3 is separated from the medium 1 plane, and is retracted by distance G. In such a way, it is possible to prevent the dust or the head crash due to the sliding occurring by preventing the contact and sliding of a magnetic head H with the medium 1 plane from occurring.
