A battery protection system for a battery having a switching mechanism positioned intermediate to the positive terminal and an electrical load of the battery. A controller manipulates the switching mechanism between an open position and a closed position, the closed position connects the electrical load to the battery and the open position disconnects the electrical load from the battery. The battery protection system utilizes a battery state-of-charge detection system, which instructs the controller to open the switching mechanism when the detection system detects a battery state-of-charge that is lower than a threshold value. The battery protection system is also equipped with a vehicle status detection system, which instructs the controller to close the switching mechanism when a vehicle startup condition is detected by the vehicle status detection system.

A disk device comprising; a head for at least reading a disk; an actuator for positioning said head at a specified position on said disk: a demodulation circuit for demodulating the position information on said disk that is read by the head; and a control circuit for calculating the amount of control for said actuator according to a position error between said demodulated position and a target position; wherein said control circuit corrects said position error by a set position gain according to the offset from the center of the track of the target position, then calculates the amount of control for the actuator, that drives said head, according to said corrected position error, wherein said demodulation circuit corrects the offset signal of the position information by a sensitivity gain that is set for a track number in the position information. 10. The disk device of claim 9 wherein: said control circuit generates permission for said head to read or write according to said corrected position error. 11. The disk device of claim 9 wherein: said control circuit adds a sine wave to said position error to change said offset position, and measures the values for the position gains at each offset position. 12. The disk device of claim 9 wherein; said control circuit calculates the amount of control according to said corrected position error by using said position error as the correction position error during seek control, and the amount of control a
