摘要： In a method for writing data to a disk drive, a selected portion of a surface of a rotating disk of the disk drive is contacted with a designated contact region of a slider. An aspect of the contact is controlled to regulate frictional heating of the selected portion such that a magnetic field required to write data to the selected portion is reduced to a level which permits writing of data in the selected portion. Data is written on a frictionally heated track in the selected portion.

摘要： A disk drive for storing data includes a drive housing, a storage disk that is rotatably coupled to the drive housing, a slider assembly positioned near the storage disk, and a drive circuitry. The slider assembly includes a head that interacts with the storage disk during a data transfer operation. The drive circuitry performs a performance test on the head at a first HtD spacing and at a second HtD spacing that is different than the first HtD spacing while the drive is operation. The slider assembly includes a slider mover that moves the head between the first HtD spacing and the second HtD spacing. The slider mover can move the head to the first HtD spacing during the data transfer operation if the result of the performance test is a first test result and the slider mover moves the head to the second HtD spacing during the data transfer operation if the result of the performance test is a second test result.

摘要： A disk drive includes a rotatable storage disk, a suspension, and a slider assembly. The slider assembly includes a slider body, a first slider deformer and a second slider deformer. Activation of the first slider deformer deforms the slider body, and activation of the second slider deformer deforms the slider body. Further, the slider deformers can be independently controllable. The read element is positioned near the first slider deformer and the write element is positioned near the second slider deformer. Activation of the first slider deformer adjusts a read head-to-disk spacing of the read element and activation of the second slider deformer adjusts a write head-to-disk spacing of the write element. Further, activation of the first slider deformer does not significantly influence the write head-to-disk spacing and activation of the second slider deformer does not significantly influence the read head-to-disk spacing.

摘要： Systems and methods from loading/unloading a data head for a disk drive provide for more efficient use of disk space. A method of loading/unloading a data head for a disk drive comprises determining a disk phase of a spinning disk arrangement, determining a loading/unloading position based on the disk phase, and loading or unloading the data head on or from, respectively, the spinning disk arrangement based on the determined disk phase. The determining a disk phase may be based on zero crossing of voltages for a three-phase motor associated with the spinning disk arrangement.

摘要： A method of determining side track erasure in a disk drive having a disk and a transducer. A target track and one or more side tracks proximate to the target track on the disk are selected, and recording parameters for recording signals on the target track and each side track with the transducer are selected. Thereafter, signals are recorded on each side track and then signals are recorded on the target track multiple times. A reduction in the integrity of the recorded signals on each side track due to recording signals on the target track multiple times is detected, and the detected reduction in the integrity of the recorded signals on each side track represents the amount of the erasure of the recorded signals on the side track. Recording parameters are changed based on the signal integrity reduction to minimize side track erasure.

摘要： A novel method and apparatus is provided for printing magnetic patterns using heat assisted magnetic recording (HAMR). The apparatus includes an array of probes that is arranged in a predetermined pattern, such as a servo pattern. The array of probes is brought into contact, or near-contact, with a magnetic recording medium that has been bulk erased substantially along an initialization direction. Each probe is energized so as to heat its respective contacted (or near-contacted) region of the recording medium above a threshold temperature. An external magnetic field is applied to the heated regions in a direction that is substantially opposite from the initialization direction. The strength of the external magnetic field is chosen to be greater than the coercivity of the recording medium at the threshold temperature, but less than the coercivity of the recording medium at room temperature. As a result, only magnetizations in the heated regions become aligned with the external field.

摘要： Instead of using discontinuous step functions or pulses to drive a laser of a TAR enabled disk drive between on and off, a fixed modulation frequency may be used that alternates between a high and low laser power such that the radiation source is always delivering heat to the magnetic media when writing data to the magnetic disk. The magnetic field of the write pole may be synchronized to the modulation frequency of the radiation source to ensure that the radiation source heats the magnetic media proximate to the write pole above the grain freezing temperature when the Zeeman energy produced by the magnetic field of the write pole exceeds the thermal energy of the magnetic media.
