Patent ID: 7198478

Claim:
An apparatus for treating a disc plate, the apparatus comprising: a transfer mechanism arranged to transfer a mold disc plate obtained through an injection molding; a disc bench arranged to receive the mold disc plate transferred with the transfer mechanism; a spin driver arranged to spin the mold disc plate on the disc bench when a temperature of the mold disc plate is higher than 90° C., to thereby spin the mold disc plate; in which the mold disc plate becomes the disc plate at not higher than 90° C.; a warp measuring device for measuring a warp of the disc plate when the temperature of the mold disc plate is reduced to not higher than 90° C.; and a converter-controller for converting and controlling a datum, the converter-controller taking the following operations of: analyzing the warp of the disc plate, determining one of the following two of the mold disc plate, in accordance with a dimension of the analyzed warp of the disc plate: one of a spin speed, a spin time and a spin speed rise time, and a combination of the spin speed, the spin time and the spin speed rise time, and transmitting a control signal to the spin driver, the control signal controlling one of the following two of the mold disc plate: one of the spin speed, the spin time and the spin speed rise time, and the combination of the spin speed, the spin time and the spin speed rise time.
