    摘要： Track addresses for respective recording surfaces of a hard disk drive are input from a main controller 122 to pattern generation sections 130 of a pattern generator. The pattern generation sections 130 generate servo patterns corresponding to the track addresses. The generated servo pattern data are temporarily stored in pattern memories 131. A transfer control circuit 132 reads out, in parallel, the servo pattern data in the pattern memories 131 in synchronism with a servo clock. Output signals from the pattern generator 122 are supplied to recording elements of servo heads 113 via write amplifiers 121, and servo patterns are written to the recording surfaces in parallel. As a result, positional deviations between servo-tracks with the same track address due to alignment errors of the head assembly can be corrected, without the need for complicated track management firmware.

    摘要翻译： 将硬盘驱动器的各个记录面的轨道地址从主控制器122输入到图案发生器的图案生成部130。 图案生成部130生成与轨道地址对应的伺服模式。 生成的伺服模式数据被临时存储在模式存储器131中。传送控制电路132并行地读出与伺服时钟同步的模式存储器131中的伺服模式数据。 来自图案生成器122的输出信号经由写入放大器121被提供给伺服磁头113的记录元件，伺服图形被并行地写入记录表面。 结果，可以校正由于头部组件的对准误差而具有相同轨道地址的伺服轨迹之间的位置偏差，而不需要复杂的轨道管理固件。

    摘要： A magnetic data embedding system (or disk servo writer) includes a stack with a master disk (3) and a plurality of magnetic disks (4) mounted on a shaft of a spindle motor (6), and a rotary positioner (11) which integrally holds one or more read-only heads (71 to 74) for reading the master disk and a plurality of groups of servo heads (101 to 104) and which simultaneously turns both of the kinds of heads. The groups of servo heads have access to the top and bottom sides of the magnetic disks. The servo heads are made carry out writing to the same (top or bottom) side of each of the disks in parallel, within assigned track ranges for the respective servo heads. In order to make the servo heads on the same side of the disks carry out writing correctly in their assigned track ranges in several of the disclosed embodiments, an address correction data memory (23) supplies information about track position errors between the read-only heads and their associated servo heads to a servo head address deriving unit (24), which corrects track addresses of items of servo information read by the read-only heads and transmits the corrected track addresses to a servo pattern generator (9) to make the servo heads write the corrected address. This shortens the time needed for writing servo patterns to magnet disks with high density and high accuracy.

    摘要： A magnetic pattern of a master disc is transferred to both sides of a magnetic recording medium with no displacement. The origin of a magnetic recording medium can be determined by observing the inner or outer periphery of the magnetic recording medium. Back-side alignment marks are formed on the front side of the magnetic recording medium based on the origin thus determined. The back-side alignment marks can be observed with a microscope and front-side alignment marks for the magnetic recording medium can be provided on the back side of the magnetic recording medium. The alignment marks provided on the front/back sides of the magnetic recording medium are aligned with the corresponding alignment marks provided on the master disc, and a magnetic pattern formed on the soft magnetic material of the master disc is can be transferred to the magnetic recording medium.

    摘要： A method of controlling magnetic recording in a magnetic recording medium and a control device for the same provides a symmetrical transferred signal waveform of equal magnitude with good reproducibility and performs magnetic transfer with high reliability. In performing initial magnetization prior to performing transfer magnetization, an AC magnetic field, the polarity of which changes in the perpendicular direction Y (or both in the perpendicular direction Y and parallel direction X), is applied to the recording surface of the magnetic recording layer of a magnetic recording medium, and the intensity of the AC magnetic field is gradually decreased with time, to demagnetize the entire magnetic recording layer.
