    摘要： A disk controller and method thereof having a configuration where when a disk apparatus fails, information on the failed disk apparatus is prevented from unauthorized access including a read operation. The disk controller in a disk system connected with a plurality of disk apparatuses includes a control information storage area overwrite unit issuing an instruction to overwrite a control information storage area of a disk apparatus with a predetermined value when a failure of the disk apparatus is detected.

    摘要： High-accuracy position signals are obtained by correcting nonlinear position sensitivities of two phase signals demodulated from two-phase servo information, into linear ones. A position sensitivity adjusting unit detects the signal level at the intersection of position signals N and Q having different phases by a predetermined track pitch which are demodulated from read signals of two-phase servo information buried and recorded in a disk medium and makes an adjustment of the gain of an AGC amplifier so that the intersection signal level coincides with a predetermined level. A sensitivity correcting unit corrects into linear position sensitivities the nonlinear position sensitivities approximated by sine functions or cosine functions relative to the actual track position X of the two position signals N and Q output from the AGC amplifier.
