Abstract:
An optical storage and retrieving apparatus, comprising:a carry means for carrying and selectively rotating an optical storage medium; a driving means for controlling said carry means operating at a rate; a data read/write means for emitting an incident light signal to said optical storage medium and receiving a reflecting light signal reflected from said optical storage medium; a guider for supporting said data read/write means to move thereon; a servo control means for controlling a velocity and a braking slope of said data read/write means moving along said guider, said servo control means storing a tracking loop gain; a central processing unit (CPU) being operatively connected to said servo control means and said driving means respectively as to control said servo control means and said driving means, so that the recorded contents of said optical storage medium are retrieved; a temperature control means, responsive to a temperature of the optical storage and retrieving apparatus, for generating a compare signal; and whereby said central processing unit, responsive to said compare signal being greater than a predetermined value, lowers said velocity.
