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.
摘要翻译：文件直接在父磁盘装置和子磁盘装置之间传送。在一个实施例中，母磁盘装置具有主机模式执行程序，而子磁盘装置能够像普通磁盘装置一样在设备模式下运行。母磁盘装置具有包括专用跳线块的操作模式设定单元。在母磁盘装置中使用的MPU执行主机模式执行程序以将母磁盘装置置于主机模式。在激活时，MPU参考专用跳线块的逻辑，以在主机模式下开始运行。 MPU控制母磁盘装置将文件直接传送到子磁盘装置。因此，该文件可以在父磁盘和子磁盘设备之间进行传输，而无需主计算机的干预。

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.

摘要： Embodiments in accordance with the present invention relate to suppressing effects of the rotational jitter of a rotating medium during self-writing of patterns on the medium. In one embodiment, patterns are written on a track TE first. While a clock frequency is modulated using the difference between the readout time and target time of each pattern PE on the track TE, patterns PF are written on a track TF after a calculated delay time from the readout of each pattern PE. During pattern writing on the track TF, any timing errors of the patterns PE are stored into memory. While the target time for each pattern PF on the track TF is being corrected using the stored timing errors of the patterns PE and the clock frequency is being modulated using the difference between the readout time and corrected target time of each pattern PF, patterns PG are written on a track TG after a calculated delay time from the readout of each pattern PF.

摘要： Embodiments of the present invention provide a method of forming an initial servo-pattern for self servowrite, insusceptible to constraints of an output resolution of a driver circuit for driving an actuator, and a dynamic range. According to one embodiment, a cluster pattern made up of pattern blocks, each including a burst pattern, is written by use of a write element by pressing a head-support mechanism to a crash-stop, and a pattern block is newly written with a read element in states of being positioned at an inner peripheral side edge of the cluster pattern, an outer peripheral side edge thereof, and the center of two burst patterns included in the cluster pattern, respectively, thereby increasing a width of the cluster patterns in stages, so that an initial servo pattern for use in a propagation action is formed.

摘要： Embodiments of the invention provide a method of testing/adjusting magnetic disk devices, in which the method allows the tests/adjustments to be conducted by solving problems due to the data sizes and characteristics of test/adjustment programs. After assembly of a magnetic disk device, setup of various parameters, magnetic disk defect registration, and other test/adjustment steps are executed. Execution of the test/adjustment programs does not require a special test apparatus since they are executed in the magnetic disk device to be tested. In addition, the test/adjustment programs are formed up of multiple phases, and each phase is sequentially executed. Adoption of this program structure keeps the tests/adjustments clear from restrictions due to the data sizes and characteristics of the test/adjustment programs.
