Title: Magnetic disk device
Inventor: HACHITANI TOSHIYUKI
IPC: G11B33/14
Filed: 1994-03-18
Abstract: PURPOSE:To prevent off-track caused by the positional deviation of a magnetic head and the construction of a magnetic disk by jointly using spacers different in thermal expansion coefficient between the magnetic disks. CONSTITUTION:The magnetic disks 3 consist of uppermost and lowermost first disks 30 and plural second disks 31 having a servo surface by laminating them on a flange part 100 at even intervals. A first spacer 11 is comes into contact with the first disk 30 and constitutes an interval, and a second spacer 28 is comes into contact with the second disk 31 and constitutes an interval. Thus, an off-track phenomenon caused by the positional deviation of the magnetic head 4 caused by the difference of the thermal expansion coefficient between a head arm 21 and a bearing 22 when a temp. is lowered and the contraction of the magnetic disk 3, is reduced by the difference of contraction amounts between the first disk 30 and the second disk 31 to prevent the off-track.
