Disk drive system employing effective disk surface stabilization mechanism

An optical information recording device comprising:

• a driving part driving a flexible optical disk;
• an optical writing part optically writing information onto a record surface of the optical disk;
• and
• a stabilization part, stabilizing vibration of the optical disk along the rotation axis direction of the optical disk by means of pressure difference of air flow at a portion on which information writing/reading is performed, provided on a single side of the optical disk opposite to a side on which information recording/reproducing is performed,
• wherein said optical writing part and stabilization part are opposed to one another through the optical disk, and wherein said stabilization part is provided only on said single side of the optical disk.

An optical recording/reproducing device comprising:

• a driving part driving and rotating a flexible optical disk;
• a pickup performing optical writing/reading onto a recording surface of the optical disk;
• a stabilization guide member provided only on a single side of the optical disk opposite to a side of a recording surface, and stabilizing surface vibration of the optical disk at a portion on which writing/reading is performed by means of pressure difference of air flow;
• and
• an adjustment control part adjusting a mutual position along the disk recording surface between the stabilization guide member and pickup along the recording surface of the optical disk according to the rotation speed of the optical disk.
