Disk drive and sealing member

A disk drive comprising:

• a carrier into which is loaded a cartridge in which a disk-shaped recording medium is rotatably accommodated and in which an opening for exposing a center portion of said disk-shaped recording medium is formed in a bottom surface thereof,
• a rotation table which enters from said opening of said cartridge loaded in said carrier, clamps said disk-shaped recording medium at said center portion and rotates said disk-shaped recording medium,
• a resilient sealing member which is attached to said carrier and prevents air containing dust from being sucked into said cartridge through said opening due to rotation of said disk-shaped recording medium, wherein
• said sealing member includes an annular base portion and a lip having a shape projecting from said annular base portion and flaring outward,
• said lip is pushed against the bottom surface of said cartridge so as to surround said opening of the loaded cartridge, and
• said base portion includes a part located inside said lip which is attached to said carrier, wherein:
• said lip includes first and second lips, wherein
• said first and second lips project from a top surface of said base portion,
• said first lip is located outside said second lip,
• a height of said first lip from a center portion of said base portion is higher than a height of said second lip from the center portion of said base portion when said cartridge is not loaded, and
• said first and second lips contact the bottom surface of said cartridge and the heights of said first and second lips from the center portion of said base portion are the same when said cartridge is loaded.
