<p>Since the gate construction in a disk device having slot-in format is a single layer of felt in which a single article slit is formed, but the disk maintenance force is weak, and variable. The objective is to provide, on the gate 2 of the disk device 3, a 1st elastic felt 6 on which is formed a single article slit 4 and multiple intersecting slits 5, and a 2nd felt 7 which is fixedly adhered to the rear surface of the 1st felt 6, the elasticity of which is weaker than that of the 1st felt 6. A surface sheet 9 on which is formed a disk transmitting aperture 8 may be also fixedly adhered to the front surface of the 1st felt 6. In order to adjust the hardness by weakening the elasticity of the 2nd felt 7, on the 2nd felt 7, a greater number of intersecting slits 5 may be formed than are existence on the 1st felt 6. In addition, multiple cutouts 10 may also be formed on the single article slit 4 of the 2nd felt 7. In addition, the fore and aft thickness of the 2nd felt 7 may be made to be thinner than that of the 1st felt 6.</p> |
