Title: Method for reducing friction coefficient of disk in fixed disk device
Inventor: YOKOZAWA TERUHISA
IPC: G11B19/04
Filed: 1990-02-13
Abstract: PURPOSE:To easily reduce the friction coefficient of a disk in operation of a disk storage device by rotating a disk whose surface is covered by means of a carbon protective film at the speed of <=10 cm/second in a state in contact with a head. CONSTITUTION:A low film 13 and an upper film 14, both of which are composed of transition metal or the alloy, are provided for two layers as magnetic recording medium on the surface of the substrate 11 of the disk 10 through a ground film 12 composed of nickel, etc. Then, the disk 10 is rotated at the speed of <=10 cm/second, preferably, <=0.3 cm/second, in the state where the head 20 is brought into contact with the disk 10 whose surface is covered by the carbon protective film 15. Thus, carbon is selectively retransferred from the head 20 to an activated edge surface in a carbon film surface where the friction coefficient is increased and the non-activation of the edge surface is promoted. Thus, the friction coefficient can be reduced in a short time even if the friction coefficient of the disk 10 is considerably deteriorated.

Title: Variable ratio magnetic resonance selective exciting method and apparatus for reducing rf power and specific absorption ratio
Inventor: SUTEIIBUN EMU KONARII
IPC: A61B10/00
Filed: 1988-02-15
Abstract: PURPOSE: To reduce RF power and a peak amplitude relative to a desired flip angle without remarkably increasing the time width of the Rf pulse, by varying an amplitude so as to be inversely proportional to a change of increased pulse width relative to an RF pulse part while an RF exciting amplitude is changed. CONSTITUTION: Fig. 4 shows a constant rate pulse 40 and a Z grade given during application of the pulse. The time width of the pulse is shown together with its relative amplitude. In Fig. 5, a variable rate pulse 44 is shown, wherein the peak 46 of this pulse is reduced by a coefficient 4, and the time width of the reduced peak part is increased by the same coefficient. With a decrease in the peak amplitude of selected excited pulse, a magnetization grade G given during an interval for applying the RF pulse should be reduced in order to maintain a desired intercept selection. In Fig. 5, not only the peak amplitude 46 is reduced but also the amplitude of side ropes 48 and 50 is increased, and also a time cycle for giving the side rope is reduced incidentally. Consequently, while a net reduction in the total pulse width is realized, the peak amplitude is reduced to 1/4.

In the processor 10, the set value of the bending pressure is determined so as to obtain the aim final sheet crown in consideration of the shape blind sector; therefore, the actually measured value is compared with the aim crown value depending on the signal produced from the detector 14. If these two values are different, the set value of the bending pressure is corrected by using the detected sheet crown value, and the final sheet crown value is controlled to the aim  sheet crown value. According to this method, the passability of the sheet is stabilized, and the improvement of the yield and quality can be contrived.
