Title: Magnetic disk apparatus and its magnetic-head positioning device
Inventor: NISHIMURA TOMOYUKI
IPC: G11B21/10
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To enhance the positioning control operation of a magnetic head by a method wherein the gain of an actuator for fine adjustment is measured, the magnetic head is positioned in a positioning region in which servo information is written on a magnetic disk medium and which is used to measure the gain of the actuator for fine adjustment and the control characteristic of the actuator for fine adjustment is adjusted on the basis of the measured result of the gain. SOLUTION: An actuator-gain measuring device 2 for fine adjustment measures the gain of a piezoactuator on the basis of the difference between a position error signal 23 and a piezoactuator drive signal 18 when a magnetic head 14 is positioned in a positioning region used to measure the gain of an actuator, for fine adjustment, on a magnetic disk medium 15. When the gain is within a proper range, a piezoactuator gain signal 16 is output to a magnetic- head positioning controller 4. When the gain is outside the range, it is regarded as a measuring abnormality, and the gain signal 16 is not updated. Without increasing the bandwidth of the magnetic-head positioning controller 4, a head positioning error amount is reduced, and an S/N ratio can be ensured.

Abstract: PURPOSE:To make always a normal memory cell group including a defective bit non-selective without complicating a process by constituting a selecting means of the normal memory cell group of a decoder circuit, an electric conducting means and a monostable latch circuit and providing a leakage path such as a high resistance means. CONSTITUTION:If a defective bit is included in a normal memory cell array 31, since a link fuse 3 is blown by a laser or the like, an output 29 of an NAND decoder 28 is insulated electrically from the monostable latch circuit 30 and the output 27 of the monostable latch circuit 30 keeps an ''L'' level at all times. This is because a P channel transistor (TR)24 is turned on by impressing a power-on reset pulse 26 to the gate of the P channel TR24 at power on, input terminal 13 of said CMOS inverter is charged to an ''H'' level, the output 27 of the monostable latch circuit 30 is set to an ''L'' level and held. Thus, column selecting TRs 9, 10 are cut off, bit lines 7, 8 are disconnected respectively from I/O lines 5, 6 and the normal memory cell array 31 has no relation with the read/write of the memory.
