Abstract

The invention relates to an electric disk and method utilizing a backup power supply to execute data destruction, wherein the electric disk comprises an electric disk body, and further comprises an intelligent backup power supply comprising a charging circuit, an energy storage element, a power supply control circuit, a data destruction pulse generation circuit and an automatic discharging circuit; the charging circuit is connected with the energy element also connected with the power supply control circuit, the data destruction pulse generation circuit and the automatic discharging circuit are arranged between the power supply circuit and the electric disk body; the method is as follows: the power supply is controlled by the power supply control circuit; a high electrical-level triggering signal is generated by data destruction pulse; data destruction action is executed by the electric disk body; after that, a feedback signal is provided; and the automatic discharging circuit provides a switch-off signal for the power supply control circuit, which is followed by end. According to the invention, the data destruction is executed by the backup power supply, so that the data destruction function can be finished by the electric disk under both of electrified or non-electrified conditions.

Description

technical field [0001] The invention relates to an electronic disk and a method for destroying data by using a backup power supply, in particular to a method for storing energy through an electric storage device, which can save the data on the electronic disk in case of emergency, regardless of whether the system is charged or powered off. The destroyed electronic disc and its method. Background technique [0002] The electronic disk with data destruction function is a widely used data storage device, which is applied in a highly secure environment. At present, there are many types of electronic disks with the function of destroying data, but there is no electronic disk that performs the function of destroying data when the system is powered off. Therefore, in order to adapt to various situations and reliably execute the data destruction function, there is a strong demand to ensure that the electronic disk can complete the data destruction function even when the system is p...
