Abstract
A magnetic storage device capable of recording a drop height and an electronic device using the same are presented. The magnetic storage device includes: a G-sensor, installed in the magnetic storage device, for outputting a first trigger signal when the magnetic storage device starts to drop and outputting a second trigger signal when the magnetic storage device stops dropping; a timer, for calculating a duration between the first trigger signal and the second trigger signal, and recording the duration as a drop time; a logic operation processor, having a built-in height calculation formula, for calculating a drop height according to the drop time; and a memory unit, for storing the drop time and the drop height. An electronic device using the magnetic storage device is also presented, which is capable of record the actual drop height when a drop event occurs on the electronic device.
