Granted: 2001-01-21
Abstract: An integer Z101 is divided by an integer I102 to obtain a remainder R109. The integer I102 includes a polynomial of power of a basic operational unit of a computer. In this way, the integer I for divisor is limited based on the basic operational unit of the computer, and thus, a shift operation, which is required for a conventional operation method, can be eliminated. The remainder can be calculated by only addition and subtraction. Accordingly, a code size becomes compact and the remainder of the integer can be calculated at a high speed.

Title: Adaptive servo gap detection for timing based servo
Inventor: BUI NHAN XUAN
IPC: G11B20/10
Filed: 2000-05-12
Granted: 2002-11-11
Abstract: Disclosed are a method and a detector for adaptively detecting servo gaps in a timing based servo pattern prerecorded on a variable velocity media. The timing based servo pattern has groups of repeated pairs of non-parallel transition stripes arranged in bursts, the bursts separated by servo gaps whose length is variable. A servo system sensor senses the transition stripes in the longitudinal direction of the media. A group interval detector coupled to the sensor detects the timing interval between the same slope transition stripes of two sequential groups of bursts. A divider divides the detected group timing interval by a predetermined divisor to provide a divided timing interval gap detection threshold. A sequential stripe interval detector coupled to the sensor measures the timing interval between stripes, and a comparator compares the divided timing interval and the timing interval, identifying a servo gap upon the measured timing interval at least equaling the gap threshold. The detector responds to ""valid"" signals which indicate the validity of the detected group timing interval, repeating operation of the divider to update the gap threshold, and repeating operation of the comparator with the updated gap threshold to continue to identify the servo gaps.
