Abstract: A method for driving a movable component of a hardware device to move a driving distance includes the steps of: (1) adjusting at least one of the former time and the latter time according to an advancing time so that a sum of the former time and the latter time is substantially equal to the advancing time; and (2) driving the movable component to the driving distance by the former force for the former time and by the latter force for the latter time.

Abstract: A method for driving a movable component of a hardware device includes the steps of: (1) driving the movable component to move the driving distance by the former force to determine a base time; (2) setting a reference time, wherein the reference time is smaller than the base time; (3) determining a former period according to the reference time, and determining the former distance and the latter distance according to the former time, the former force and the base time; and (4) determining a latter period according to the latter force and the latter distance, wherein the movable component is driven by the former force for the former period and then is driven by the latter force for the latter period.

Abstract: The invention is to provide a method for determining a maximum storage capacity of an optical information record medium having a pregroove on which predetermined address codes are marked. The method is performed by detecting the last physical predetermined address code of the predetermined address codes. The maximum storage capacity is represented in terms of time by a time value representative of the detected last physical predetermined address code.

Abstract: A circuit for providing the function of a dual port FIFO circuit including a first bank of single port random access memory, a second bank of single port random access memory, apparatus for sequentially writing every other piece of sequential data to an alternate one of the first and second [memory] banks of single port memory, and apparatus for simultaneously reading the earliest written piece of sequential data from the one [each] of the first and second [memory] banks of single port memory not being written during the period data is being written to the other of the [memory] banks of single port memory. By using two banks of single port memory, the cost of dual port memory typically used for a FIFO circuit is substantially reduced.
