摘要： Method and apparatus for compensating for errors in the location of servo frames in a disc drive, the servo frames providing control inputs to a servo loop of the disc drive. Each servo frame includes an additional compensation field to which a compensation term is written, the compensation term indicative of the average radial error in the location of the servo frame. The compensation term is determined by measuring the radial distance between adjacent servo frames over a plurality of revolutions of the disc and averaging these measured radial distances. The compensation terms are thereafter used in conjunction with position information from the servo frames to control the position of the head. The compensation term facilitates the elimination of repeatable, random errors in the locations of the servo frames, causing the head to nominally follow a circular path about the disc, regardless of the errors in the locations of the servo frames.

摘要： A method and system of identifying and compensating for the cumulative effect of once per revolution, OPR, timing errors by modulating the size of an inter-sector runout (ISR) field between servo sectors. The ISR field is part of an inter-sector gap (ISG) field. The method begins when the nominal data field frequency is increased by one-half of the spin speed tolerance to guarantee adequate data field tolerances at the fastest portion of the timing OPR error curve. The ISR field is added to the disc format and maintained as a rotationally varying field. The ISR field is varied rotationally from a minimum of zero to a maximum equal to the timing OPR error tolerance. The size of the ISR field is varied rotationally based upon a calibration table that is used to identify the location of the disc drive head and to compensate for the appropriate timing OPR error at that location. The remainder of the ISG field is used to compensate for fixed timing errors.

摘要： A digital phase detector that conducts pump up and pump down control signals to a charge pump, wherein each of the control signals has pulses that have a substantially 50/50 duty cycle characteristic when the two input signals, i.e., the input data signal and the feedback clock signal, are substantially in phase. This substantially 50/50 duty cycle output reduces, if not eliminates, inherent problems related to the turn-on delays of the charge pump while maintaining a locked condition. The phase detector may further include an intelligence to detect and handle other situations, such as missing data pulses.

摘要： An apparatus and method of reducing the size of a servo burst and thus increasing the disc surface available for data storage is accomplished by uniquely encoding track information in the gray code of a servo burst on a disc. Each track has a unique sequential track identification number assigned to it. A plurality of sets of servo sectors on each track are encoded with a modulo operation of the track identification number for the track each using a unique modulus. Preferably the sectors are grouped into two sets, i.e., even numbered sectors on each track are modulo encoded with a first modulo operation of the track identification number for the track using a first modulus and odd numbered servo sectors on each track are modulo encoded with a second modulo operation of the track identification number for the track using a second modulus. Decoding the absolute track address is accomplished by decoding the modulo numbers and comparing the even sector modulo numbers to the odd numbered sector modulo numbers.
