摘要： Embodiments of the present invention provide a magnetic disk drive capable of controlling write/read positions by a method that takes the disturbance in the circumferential direction of a magnetic disk into consideration, thereby making it possible to improve the positioning accuracy. A magnetic disk drive in accordance with an embodiment of the present invention comprises: a magnetic recording medium on which information is written to each track thereof, the recording medium having a servo signal formed in the each track at specified intervals; a magnetic head including a read head for reading a signal from the magnetic recording medium, and a write head for writing information to the magnetic recording medium. At the time of writing/reading information by the magnetic head, a servo signal is detected from among signals read out by the read head. Information about intervals of the detection is continuously acquired on the basis of the information about the servo-signal detection intervals that have been continuously acquired. The amount of rotational fluctuations of a magnetic disk is calculated; and if the amount of rotational fluctuations exceeds the predetermined allowable range, specified processing relating to at least one of writing and reading is stopped.

The magnetic disk controller includes a first buffer and a second buffer each of which temporarily stores data that is to be written into at least one sector of the magnetic disk. The magnetic disk controller includes an encoding unit that encodes the data stored in any of the first buffer and the second buffer into data representing a signal to be applied to the magnetic disk. A data width M between the encoding unit and the first and second buffers is at least equal to twice a data width N between the interface and the first and second buffers.
