BASE PLATE FOR A HARD DISK DRIVE CAPABLE OF MINIMIZING PROCESSING TIME, A MANUFACTURING METHOD THEREOF, AND THE HARD DISK DRIVE

摘要

PURPOSE: A base plate for a hard disk drive, a manufacturing method thereof, and the hard disk drive are provided to form an eddy flow due to disk rotation during press or forge processes.;CONSTITUTION: A disk is arranged on a disk arrangement unit(110). A head mounting unit(120) is formed on a lower part of the disk arrangement unit. A head driving unit(300) is arranged on the head mounting unit. The head driving unit provides driving power to a magnetic head. After the disk arrangement unit is punched, the punched part is lifted to form an eddy flow preventing wall(140). The eddy flow preventing wall forms a gap with an external outline of the disk. The eddy flow preventing wall suppresses an eddy flow due to the disk rotation.;COPYRIGHT KIPO 2012
