PURPOSE:To improve the recording and reproducing capability with simple constitution by adopting the constitution that plural arms coupled with a roller via a buffer to a slot of a disk peripheral prevent the deflection of a disk. CONSTITUTION:A slider arm 6 is slided in a fixed arm 7 and a buffer spring 9 is arranged to an air gap between the slider arm 6 and the fixed arm 7. The slider arm 6 and the fixed arm 7 constitute a support member supporting the roller 5 and the spring 9 being the buffer member. When the disk 1 is driven, the roller 5 is turned while being fitted into a slot 10. The roller 5 and the slot 10 are formed triangle and energized by the spring 9 at all times, have the aligning action and the slot 10 formed at the side face of the peripheral of disk is an isosceles triangle having the same cross section as the maximum diameter of the roller 5. Through the constitution above, the recording and reproducing capability is improved. |
