Abstract

PURPOSE:To attain the highly accurate self-formatting by using a linear pulse motor, holding a prescribed positioning accuracy, recording first the servo information, executing the servo based on the servo information and recording the data information. CONSTITUTION:Servo information 11 is recorded while a half track is dislocated from a data track 12. As the feeding mechanism of a magnetic head, a linear pulse motor is used and a torque curve in respective phases of the linear pulse motor is measured beforehand. By setting the value added to respective phases of the exciting current at this time, the prescribed feeding information is realized and the information 11 is recorded by the feeding pitch of one track. After the information 11 is recorded, the servo is turned on based on the recorded information 11, and while the on track is obtained, the formatting of the data information is executed. Thus, the highly accurate self-formatting can be executed.

In recent years, a so-called data surface servo method has been attracting attention in magnetic recording media such as magnetic disks, in which servo information is recorded in defined areas on the data surface (hereinafter referred to as servo sectors). This method is considered to be suitable for achieving high track because thermal off-trunk is less likely to occur compared to the conventional servo surface servo method. Further, this servo sector is usually recorded on the magnetic disk in advance by a device called a servo track writer.

Once the servo information 11 has been recorded, Fig. 1 (B)
As shown in FIG. 2, servo is performed based on this servo information 11 and data information 13 is recorded. That is, the servo is turned on based on the recorded servo information 11 and the data information 13 is formatted while the servo is on track. Here, if data information 13 is formatted only by open-loop feeding of the linear pulse motor, the feed accuracy of this linear pulse motor will occur between servo information 11 and data information 13, and the servo will actually be turned on. In this case, errors in the feed accuracy and tracking accuracy of the linear pulse motor are compounded. However, in this method,
If only the servo information 11 is recorded in an open loop and recorded to the extent that the servo information does not overlap on the upper and lower tracks, the data information 13 recorded with the servo turned on will always be located on the correct track. As described above, there is no error problem when formatting the data information 13 only by feeding by the open loop of the linear pulse motor.
