    摘要: A method of recording a servo signal on each track of a magnetic disk includes a first signal for demagnetizing the magnetic disk and a second signal for forming the servo signal. The recording width (core width) of the magnetic head is made greater than the width of the track. Parts for recording signals and not recording signals are set in each track. The first and second signals are selected and recorded in the signal recording part, thereby to form the servo signal. Current to be conducted to the magnetic head is cut in the part for not recording signals, and the track is skipped to the next part for recording signals. When the recording of the track has ended, the magnetic head is moved to the next track, and the above steps are repeated.

    摘要: A head arm for use in a magnetic disk drive, comprising a guide arm disposed between a magnetic head and an actuator so as to transmit actuating force of the actuator to the magnetic head thereby guiding the magnetic head along a plane of a magnetic disk, a printed circuit fixed to the guide arm, and deflection compensating member for making the coefficients of thermal expansion of said guide arm and said printed circuit substantially equal to each other in at least the direction of seek of the head arm. No thermal deformation in an out-of-plane direction occurs on such a head arm regardless of any variation in the temperature of the environment in which the magnetic disk drive is installed. The head arm may also comprise a guide arm and a printed circuit formed of a moisture absorptive material and covered at all or part of its surfaces with a covering layer formed of a moisture resistive material not permeable to moisture. No deformation in an out-of-plane direction occurs on such a head arm regardless of any variation in the humidity of the environment in which the magnetic disk drive is installed. Therefore, the possibility of occurrence of off-track can be minimized.

    摘要: In a magnetic disc device, it is necessary that a magnetic head be positioned above an object data track at a high speed and with a high accuracy. This positioning operation is carried out by an actuator. In order to carry out a magnetic head-positioning operation at a high speed and with a high accuracy, it is necessary that a driving force generated by a magnetic circuit be applied to the center of gravity of the actuator. The techniques according to the present invention are characerized in that the center of gravity of the actuator and the position to which the driving force is applied are aligned with each other by regulating the distribution or position of the magnetic flux in the magnetic circuit.

    摘要: A linear actuator assembly for linearly the reciprocatingly moving magnetic heads in a magnetic disk storage apparatus. This linear actuator has a carriage for supporting magnetic heads, and a voice coil for moving the carriage. The sectional configurations of the carriage and the voice coil are equalized, thereby enabling the transmission of the driving force from the voice coil to the carriage without any eccentricity. This linear actuator also has a vibration absorbing mechanism for absorbing vibrations caused when the linear actuator operates, and a runaway prevention mechanism for limiting the movable range of the carriage.

    摘要: It has been discovered that lysozyme in the blood is concentrated into the albumin fraction when the blood is fractionated by the alcohol fractionation method at lowered temperature or the ammonium sulfate fractionation method. Lysozyme can be produced by contacting the albumin fraction with a weakly acidic cation-exchanger such as CM-cellulose to adsorb selectively the lysozyme with the cation-exchanger and then eluting the lysozyme adsorbed from the cation-exchanger.
