Abstract (en)

[origin: WO2006062511A1] A method and system for the erasing of data from a non-volatile recording medium includes a non-volatile recording medium controller, a non-volatile recording medium, and a CPU. A data pattern used in an erasure command is sent to the non-volatile recording medium a single time. Consequently, the amount of data transferred to the non-volatile recording medium controller is reduced to a minimum. After receiving the erasure command, the non-volatile recording medium controller overwrites an erasure area with the data pattern.
