Title: Disk drive apparatus having improved initialization process
Inventor: YANAGI SHIGENORI
IPC: G11B7/125
Filed: 1990-09-11
Abstract: A disk drive apparatus includes a driving circuit (14) which rotates a recording media (10) having a disk shape, and a read/write head (22) movable in a radial direction of the recording media and a vertical direction substantially perpendicular to a plane of the radial direction. The read/write head writes data on the recording media and reads data therefrom. The disk drive apparatus also includes an initialization unit (16, 18, 20) which initializes the read/write head during a period (t₁-t₅; t₁-t₄) until the recording media starts to rotate and the rotating speed of the recording media reaches a predetermined constant speed so that the disk drive apparatus is set to a read/write enable state where the read/write head is correctly positioned with respect to the recording media in order to correctly write data on the recording media and read data therefrom.

Abstract: In the process for controlling the tape thickness it has been found that the complex roll eccentricities produced by the superimposition of several interfering influences are not adequately compensated for by the control methods which have hitherto become known. To be able to compensate for even complex roll eccentricities, it is proposed to determine the transfer function of the fault signal embodying the roll eccentricity and to derive from this transfer function controller parameters on the basis of which roll eccentricity compensation signals can be calculated. Using this means, the roll eccentricities are compensated for in accordance with the principle of adaptive control.
