ABSTRACT:
A disk drive unit includes a disk stabilizer block supporting a reading and/or writing head. The disk stabilizer block is formed a surface to sealingly contact with a mating surface of the disk. At least one void is formed on the disk stabilizer block for defining a chamber around the reading and/or writing head, in which Bernoulli drawing force is generated for drawing a flexible storage medium disk. The void reduces contact area between the stabilizer block and the disk for avoiding influence of tolerance in production of the stabilizer block and influence of waving of the disk during rotation.
