摘要： A track jump control unit adds an FF signal for repetitive disturbance compensation obtained by a learning control which is used in a track-following control and a final value of an FB control low band component just before a track jump to a track jump signal to move a light spot to an adjacent track, thereby driving a carriage. As a track jump signal, a first kick pulse of a predetermined acceleration and a predetermined time, a second kick pulse which continues at a predetermined acceleration until a detection of a track zero-cross point, and a brake pulse of a predetermined acceleration (deceleration) and a predetermined time are used.

摘要： An approximate value calculating unit is provided for a storage apparatus in which a seek control is performed by speed controlling a head. When a square root arithmetic operation is needed in the calculation of a seek speed target value which is used in the seek control, the approximate value calculating unit divides a range of an input value x serving as a target of the square root arithmetic operation into a plurality of intervals, sets a polynomial of degree N to approximately output a square root {square root over ( )}x of the input value x as an approximate function every interval, and calculates the square root approximate value of the input value x by selectively using the approximate function corresponding to the interval to which the input value x belongs. Further, according to the range dividing method of the input value x, it is sufficient that the polynomial of degree N or the approximate function by the reference table is prepared only for the basic range, and there is no need to prepare the approximate function which covers the range before the input value x. Even when the square root approximate value for the input value x belonging to the range out of the basic range is obtained by executing the input scale conversion and output scale conversion, the approximate function prepared for the basic range can be used.

摘要： A learning control unit is provided between a feedback calculating unit and a driving unit. When a period for one medium rotation period is assumed to be TL, an unknown drive current function Irepeat(t) which repeats for a period of time from a start time t=0 for one medium rotation period to an end time t=TL is obtained by a learning algorithm as an approximated function I{circumflex over ( )}repeat(t) that is approximately presumed by a set of the heights Ci of N rectangular functions having interval numbers i=0˜ (N−1) whose time widths are obtained by dividing the period for one medium rotation period into N intervals. After the learning, a learning control signal I{circumflex over ( )}repeat is outputted synchronously with the medium rotation and a feed-forward control is performed. The learning control unit can be provided between a position signal detecting unit and a feedback calculating unit and can learn a position function TESrepeat(t) as an approximated function TES{circumflex over ( )}repeat(t) in a similar manner.

摘要： An image recording apparatus (1) causes a recording head (20) to move through a distance corresponding to one half of the recording width of the recording head (20) in a sub-scanning direction each time a recording drum (10) makes one rotation. This, light emitting devices (23, 24) record two line data in advance, and thereafter following light emitting devices (21, 22) record the same line data repeatedly at the same position. This increases the energy of laser light beams given to a recording position on a printing plate (P) to accomplish the recording of an image with reliability. The recording speed is not extremely decreased because not all light emitting devices (21 to 24) are used to make the repeated recordings at the same position on the printing plate (P). Further, the construction of optical systems and driving systems in the image recording apparatus is not complicated.

摘要： A control unit positions a laser beam toward a target track on a medium on the basis of a tracking error signal (TES) Y indicative of a positional deviation amount from a track center as a zero point on the basis of return light from the medium. A position signal correcting unit executes a correcting arithmetic operation using a non-linear function such as a quadratic polynomial, a quadratic monomial equation, or the like to the TES Y and outputs a corrected TES Z obtained by correcting detection sensitivity characteristics to desired characteristics so that a feedback is sufficiently performed when a lead-in control to the track center by the control unit is executed.
