摘要： An off-track retry method for recovering data incorrectly read due to a read error caused by an off-track error in a disk drive. The off-track retry method includes extracting read gain characteristics while varying an off-track amount, determining an off-track amount, i.e., off-track direction and degree, based upon the read gain characteristics, reading data using the determined off-track amount, and determining whether the read data is normal and determining whether the data incorrectly read due to the read error has been recovered based upon the result.

摘要： A hard disk drive includes a housing having a base plate and a cover plate. A spindle motor is installed on the base plate. A disk is installed on the spindle motor to store data. An actuator has a magnetic head to record or reproduce data with respect to the disk and is installed on the base plate capable of pivoting by a voice coil motor. A printed circuit board is installed on a bottom surface of the base plate. A through hole where servo track information is recorded on a recording surface of the disk is formed in the base plate, and a hole cover made of a metal plate exhibiting an electric conductivity and covering the through hole is attached to the bottom surface of the base plate to block an electromagnetic wave generated by the printed circuit board from being transferred to the inside of the housing.

摘要： A method and apparatus for controlling a hard disc drive are provided. The method comprises the steps of (a) receiving a write instruction and sensing a temperature around the hard disc drive, (b) enabling a write verify function when the above sensed temperature is below a threshold temperature and recording data on a data sector, (c) reading the above recorded data and detecting a recording error, and (d) recording data on a reserved sector when the recording error is detected in the above step (c). When the recording error is detected while recording data on a magnetic disc in a low temperature mode, then a cycle of recording, reproducing, and error detecting is repeated several times. Since a sector is reassigned, if an error is detected, and the data is recorded on that reassigned sector, recording and reproducing of the data can be carried out more reliably.

摘要： Provided is a method and apparatus for adaptively controlling the timing of servo pulses in a disk drive in consideration of the amount of spindle jitter generated when a rotational speed of a disk is changed. The method of controlling the timing of a sector pulse for write operation includes the operations of: measuring a spindle jitter value in a data write mode; generating a timing correction value of a sector pulse, which indicates a position of a sector where data is written, according to the measured spindle jitter value; and generating a sector pulse by reflecting the timing correction value of the sector pulse.
