Disclosed is a circle patterned shape for Top cover stiffness enhancement. Background; Recently, Notebook PC is downsizing. Based on this, the spece which is allocated to PC part like HDD is getting small. Additionally, low cost competition brings rigidity of PC body down. Under such condition, external force to the PC is easy to come through the HDD. 2.5inch HDD which is mounting on Notebook PC has low stiffness of Top cover compared with one for Desktop or Server. The clearance between Top cover and Disk (Top clamp) is also small. Therefore, External force makes Top cover deform and causes interference between Top cover and Disk (Top clamp).(Fig.1) Interference in read/write operation leads to critical crash. Fig. 1
