摘要

end. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a preliminary search method for minimizing a drop-down phenomenon of a hard disk drive.;I. Disclosure of Invention Technical Problem [8] The present invention provides a preliminary search method that minimizes a drop-down phenomenon, minimizes a defect rate of a test process during a manufacturing process, and prevents loss of write data in a user mode.;All. The present invention also provides a hard disk drive for recording data received from an external device connected to a disk, comprising: setting arbitrary cylinders before writing data received from the external device to a target cylinder And the head is positioned on the final target cylinder, and the received data is written.;la. An important application of the invention is that it can be used for hard disk drives.
