摘要： An optical data accessing apparatus and method for changing the access from a first data layer to a second data layer of an optical storage medium are provided. The first data layer corresponds to a first SAC value, while the second data layer corresponds to a second SAC value. A processor of the optical data accessing apparatus is adapted for: (1) generating and sending a focus off signal to a pickup control unit to disable focus control; (2) generating a target value for an SAC to adjust an SAC value from the first SAC value to the target value, wherein the target value is between the first SAC value and the second SAC value; and (3) generating and sending a focus activation signal to the pickup control unit to re-enable the focus control to focus on the second data layer while the SAC value reaches the target value.
