Title: Tracking circuit for magnetic disk device
Inventor: SEKO SATORU
IPC: G11B5/596
Filed: 1988-12-22
Abstract: PURPOSE:To move a magnetic head to a position near an object track without using an optical encoder by recording a servo signal for speed servo to the depth of the magnetic head. CONSTITUTION:When magnetic heads 11A, 11B and 12A, 12B are moved up to an object track, first a switch circuit 24 is thrown to the position (b). A continuous pattern of signals whose phase differs from each other by 180 deg. is recorded to the depth of magnetic disks 1, 2 at a border of the center of the track. Thus, when the heads 11A, 11B and 12A, 12B are located in the center of the track, the output level of an AM demodulation circuit 26 is decreased. The output of the circuit 26 is fed to a comparator 17, in which the output level is compared with a prescribed threshold level. Then a track pulse is outputted from the comparator 27, and when the magnetic head is moved in the vicinity of the object track by using the track pulse, the circuit 24 is thrown to the position of (a) and the head is moved to a just-track position by using the 2nd servo signal on the surface.

Abstract: PURPOSE:To keep off any turnover at the time of sudden turning surely by installing an inner ring floatage detecting element, and stopping any traction control by a brake when a sudden turning inner ring is floated, while constituting engine output so as to be lowered as much as the specified value. CONSTITUTION:A wheel stroke l of each wheel of wheel stroke sensors 28L, 28R, 26L and 26R, a body velocity V of a body speed sensor 27 ad a steering angle lambda are all inputted into an inner ring floatage detecting element 34, and when lateral acceleration calculated with the body velocity V and the steering angle lambda becomes larger than a certain value and the wheel stroke l of at least one wheel in inner rings at the time of turning becomes more than the setting value, it is so judged that the inner ring is floated. When the floatage is judged by the detecting element 34, any slip control by a brake is not performed and such a signal as reducing engine output is outputted to a throttle control part 33. In brief, in the case of sudden turning inner ring floatage, the engine output is lowered up to a degree where a dange of turnover in keeping the floated wheel raced intact, thereby lowering driving force in the grounded wheel, and thus any possible danger for a wheel turnover is eliminated.
