摘要： A method and apparatus are disclosed for optimizing operational performance of a disc drive. The disc drive is provided with an integrated temperature measurement circuit which provides a temperature measurement signal indicative of operational temperature of the disc drive. The integrated temperature measurement circuit is formed as part of an application specific integrated circuit (ASIC) housing additional circuitry used by the disc drive during operation. A parametric configuration circuit, operably coupled to the integrated temperature measurement circuit, identifies selected parameters for use by the disc drive to optimize disc drive performance, the parameters arranged as a plurality of parameter sets corresponding to a plurality of predefined operational temperature ranges. The parametric configuration circuit periodically measures the operational temperature of the disc drive through evaluation of the temperature measurement signal, identifies the operational temperature range in which the measured operational temperature falls, and implements the parameter set corresponding to the identified operational temperature range.

摘要： Improvements in placement of timing patterns in self-servowriting include detecting and correcting for media defects. A detector is used to detect whether a trigger pattern is within an expected location on the storage medium. If the trigger pattern is not detected, then a physical defect may be present. Thus, in one example, a false trigger pattern is generated. Additionally, a determination is made as to whether a trigger pattern is within an expected trigger pattern region. When the trigger pattern is not within the expected range, then a valid interval window may be modified to adjust the expected trigger pattern region.

摘要： Improvements in placement of timing patterns in self-servowriting include correcting for random errors. Random errors may be caused by variations in disk velocity and therefore, one technique for correcting for random errors includes reducing velocity jitter. Additionally, random errors can be corrected by improving interval control during the propagation of trigger patterns used in writing timing information on storage media. Further, random errors, in the writing of timing information, can be corrected during a single revolution of the storage media. This eliminates additional rotations, thereby providing a large capital cost savings.

摘要： The invention relates to a comprising a magnetic tape formatted by a write head, and an apparatus comprising a magnetic head unit which is movable on a transverse direction by an actuator. The write head records the magnetic tape with a pattern of servotracks ST101-ST127 which extend in a longitudinal direction. The odd-numbered servotracks contain a first servosignal and the even-numbered servotracks contain a second servosignal Sb which is phase opposition to the first servosignal. The servotracks ST103-ST113 and ST116-ST126 have a typical width W1 and form a group of two bands of N1 servotracks which are separated by a band of N2 servotracks ST114, ST115 having a typical width W2. The magnetic tape is adapted to cooperate with an apparatus comprising eight magnetic write heads. The actuator is controlled in response to the servosignals read by the heads. The center-to-center distance between the magnetic write heads is equal to four times the typical width W1 and, moreover, it holds that:N2=2, 4, 6 etc. and W2=(k+1/2)W1or N2=1, 3, 5 etc. and W2=2k.W1,where k=1, 2 etc.

摘要： In a magnetic recording medium to detect tracking error signals optically where an optical head and a magnetic head scan different tracks, two signals having phases different by .pi./2 are generated and added or subtracted. By changing the amplitude of the two signals with a changeable gain amplifying means, a phase of a tracking error signal is changed so that the servo operation is conducted at the middle of the amplitude of the tracking error signal to keep the magnetic head on track.

摘要： A device for reading and recording magnetic data includes an aerodynamically supported slider with an air bearing surface, and a transducer mounted to the slider for movement toward and away from the air bearing surface responsive to changes in the slider operating temperature. In one embodiment, the transducer movement is primarily due to a difference in thermal expansion coefficients between a transducing region of the slider incorporating the transducer, and the remainder of the slider body. In another embodiment, a strip of thermally expansive material is incorporated into the slider near the transducer to contribute to the displacement by its own expansion. A temperature control circuit, coupled to the strip of thermally expansive material or to a resistance heating element on the slider, employs a variable current source to control the slider temperature and transducer displacement. Nominal slider operating temperatures can be set to achieve a predetermined transducer flying height, to compensate for variations in flying heights among batch fabricated sliders. Optionally, a temperature sensor can be employed to measure the slider operating temperatures and provide a temperature sensitive input to the temperature control circuit.

摘要： Improvements in placement of timing patterns in self servo writing include correcting for random and systematic errors due to geometric effects. In a disk drive having a recording head with separate read and write elements, a method for determining separation between the elements and for correcting for such errors as a function of skew angle between the head and the disk. Errors resulting from misalignment and non-parallelism of the elements as well as misalignment of the head on it its actuator are also detected and corrected. Errors due to changes in rotational velocity of the disk and misplacement of timing patterns with respect to adjacent timing patterns are detected and corrected. In general, a single revolution process may be used to both write and detect random errors on each track and corrected on subsequent tracks.

In preferred embodiments, the accelerometer includes a cavity formed in the slider body.

摘要： The dimension ratio t/H of the thickness t of a flexure spring to the height (thickness) H of a slider 17 is set at 0.047 or less in order to reduce the variation in crown amount due to a temperature variation. As the ratio of the thickness t of the flexure spring to the height H of the slider decreases, the stress acting in the slider due to a difference in linear expansion coefficient between itself and the flexure spring decreases and the rigidity of the slider increases relative to the flexure spring. The dimension ratio H/L of the height H of the slider to the length L thereof is set at 0.245 or more. As the dimension ratio H/L increases, the rigidity of the slider increases and the amount of deformation of the slider due to a difference in linear expansion coefficient between itself and the flexure spring decreases. In addition, the ratio A2/A1 of an actual adhesion area A2 between the slider and a slider fixing portion of the flexure spring to a possible adhesion area A1 therebetween is reduced to 0.42 or less. Moreover, a temperature compensation member is adhered to the slider or the flexure spring.
摘要翻译：弯曲弹簧的厚度t与滑块17的高度（厚度）H之间的尺寸比t / H被设定为0.047以下，以便减少由于温度变化引起的冠部量的变化。随着弯曲弹簧的厚度t与滑块的高度H的比值的减小，由于自身与弯曲弹簧之间的线性膨胀系数的差异而在滑块上作用的应力减小，滑块的刚度相对于弯曲弹簧。滑块的高度H与其长度L的尺寸比H / L设定为0.245以上。当尺寸比H / L增加时，滑块的刚度增加，并且由于其与弯曲弹簧之间的线膨胀系数的差异导致的滑块的变形量减小。此外，滑块与挠曲弹簧的滑块固定部之间的实际粘合面积A2与其间可能的粘合面积A1的比率A2 / A1减小到0.42以下。此外，温度补偿构件粘附到滑块或挠曲弹簧。
