Suspension assembly with lift tab, disk drive with the same, and method of manufacturing lift tab of suspension assembly

A suspension assembly for a disk drive, comprising:

• a support plate including a distal end;
• and
• a lift tab extending in a first direction from the distal end of the support plate,
• wherein
• the lift tab is formed to have an arc-shaped lateral cross section orthogonally crossing the first direction, and comprises an arc-shaped outer circumferential surface, an arc-shaped inner circumferential surface, a first upper end surface located between one arc end of the outer circumferential surface and one arc end of the inner circumferential surface, and a second upper end surface located between an other arc end of the outer circumferential surface and an other arc end of the inner circumferential surface, and
• a first angle made between the outer circumferential surface and the first upper end surface is less than a second angle made between the inner circumferential surface and the first upper end surface.
