摘要： Embodiments of the invention relate to measuring characteristics of a head with an actuator put in a state of being pushed against a crush stop. In one embodiment, with a head placed on an innermost ID side or with the current of a VCM sustained at a magnitude I_mid, a burst pattern is written onto a recording disk. At this stage, the gain of a VGA is equal to its maximum value Gmax. Then, while the current of the VCM is being changed gradually, the gain of the VCA is measured. As the current of the VCM becomes equal to a magnitude I_center, a read element of the head is positioned right above the burst pattern. At that time, the gain of a VGA is equal to its minimum value Gmin. As the read element is further moved to the OD side, the gain of the VGA again becomes equal to the maximum value Gmax. A read/write offset of the head is identified by the magnitudes I_center and I_mid.

摘要： Embodiments of the invention relate to writing servo patterns onto a recording disk with a high degree of accuracy and with correct phases in a servo-pattern-writing process. An In-Drive SSW (TSSW) process is processing to write product servo patterns onto a recording disk on the basis of time aligned patterns. In the processing to write product servo patterns onto a recording disk, time intervals between time aligned patterns already written on an ID-side track are measured, and timings to write the product servo patterns onto the recording disk on the basis of the measured time intervals are determined. Product servo patterns are then written onto an OD-side track with the determined timings relative to detections of the time aligned patterns used as references. In this way, circumferential-direction positions of product servo patterns written on a track may be aligned to the corresponding circumferential-direction positions of product servo patterns written on an adjacent track.

摘要翻译：本发明的实施例涉及在伺服模式写入处理中以高精确度和正确的相位将伺服模式写入到记录盘上。驱动内SSW（TSSW）过程是基于时间对齐图案将产品伺服模式写入记录盘的处理。在将产品伺服模式写入记录盘的处理中，测量已经写入ID侧轨道的时间对齐图案之间的时间间隔，以及基于所测量的时间间隔将产品伺服模式写入记录盘的定时确定。然后将产品伺服模式写入具有相对于用作参考的时间对齐图案的检测的确定的定时的OD侧轨道上。以这种方式，写在轨道上的产品伺服图案的圆周方向位置可以与写在相邻轨道上的乘积伺服图案的相应圆周方向位置对准。

摘要： Embodiments of the invention relate to writing servo patterns having aligned phases onto a recording disk in a process to write the servo patterns onto the disk. In one embodiment, time aligned patterns are written onto a magnetic disk on the basis of time intervals between base patterns with timings aligned to each other throughout tracks on the disk. The time aligned patterns are written onto typically servo tracks at time intervals Ts with aligned timings. Then, on the basis of these time aligned patterns, product servo patterns are written onto the disk. A time aligned pattern is written onto the disk after the lapse of a predetermined write time period since detection of a base pattern corresponding to the time aligned pattern. The write time period is determined on the basis of time intervals between base patterns on adjacent tracks.

摘要： A file is transferred directly between a parent magnetic-disk device and a child magnetic-disk device. In one embodiment, a parent magnetic-disk device has a host-mode execution program, whereas a child magnetic-disk device is capable operating in a device mode as is the case with an ordinary magnetic-disk device. The parent magnetic-disk device has an operating-mode-setting unit including a special-purpose jumper block. An MPU employed in the parent magnetic-disk device executes the host-mode execution program to put the parent magnetic-disk device in a host mode. At an activation time, the MPU refers to the logic of the special jumper block to start an operation in the host mode. The MPU controls the parent magnetic-disk device to directly transfer a file to the child magnetic-disk device. Thus, the file can be transferred between the parent and child magnetic-disk devices without intervention by a host computer.

摘要： Embodiments of the invention provide a disk drive that may perform part of a function assignment process without being connected to a special test apparatus. In one embodiment, servo data is written only into dedicated regions of a disk. A function assignment program is stored within the dedicated regions. When a processor is powered on, the processor refers to a state setter and judges whether the function assignment program is to be executed. The state setter is constituted by a nonvolatile memory or a jumper block. The function assignment program includes data relating to servo data writing based on a self-servo writing scheme, and data relating to parameter setup.
