Abstract:
1. A method of controlling an optical disk apparatus, comprising the steps of: rotating an optical disk which is flexible; irradiating light from an optical pickup to a recording layer of the optical disk on which writing/reading of information is performed; stabilizing vibration of the optical disk occurring in a rotary axial direction with a stabilizing member by using pressure difference of air flow at least on a portion where writing/reading is performed; analyzing a value of a tracking error signal of the optical disk obtained by scanning along a groove of the optical disk with use of the optical pickup; predetermining standard conditions for adjusting a positional relation between the optical disk and the stabilizing member in a three dimensional space by scanning along the grooves of optical disks having different specifications; and adjusting the positional relation between the optical disk and the stabilizing member in a three dimensional space according to one of the predetermined standard conditions about a disk corresponding to the specification of the optical disk.
