Cushioning ramp having a stepped structure for a magnetic disc apparatus
摘要:
For cushioning a shock to prevent problems such as a reading error, a ramp for a magnetic disc apparatus is made of a resin material for forming a ramp main body and a material having higher rigidity than the resin material, disc facing surfaces in the disc insertion portion for inserting a magnetic disc is provided with disc contact portions made of the high rigidity material, a bottom surface portion of a concave portion of the disc insertion portion is constructed by a combination of a bottom surface portion made of the resin material and a bottom surface portion made of the high rigidity material, and a step structure is provided by arranging the bottom surface portion made of the high rigidity material at a position moved rearward in a depth direction of the concave portion in comparison with the bottom surface portion made of the resin material.
