Abstract

PURPOSE:To reduce the time from start of the operation to the state possible of reproduction and recording, by providing a heat conductor between the disk medias and equalizing a heat expansion time constant of the disk media at the start of operation. CONSTITUTION:A spindle shaft 2 and disk media 3-7 provided on a base 1 are turned to generate the frictional heat with the air. With this heat, the media 3-7 plus head arms 9-14 start the heat expansion with a prescribed time constant respectively. Accordingly the shift of position of each head converges with a prescribed time constant according to the time constants of said disk media and arms. This converging time constant is maximum at the center data head arms 11 and 12 and minimum at the head arms 9 and 14 on the highest and lowest faces respectively. The heat of friction is discharged via the media 3-7 and the shaft 2. In this case, the time constant of the disk 5 at the center of the shaft 2 becomes maximum. In the diagram, figures 16 and 17 denotes a heat conductor and a cooler respectively.
