To provide a production method and device of an optical information record ing medium with excellent quality stability to eliminate an ignition defective phenome non for example in the DC sputter deposition of an AgInSbTe base recording films those main components are Sb and Te.

(1) The production method of the optical information recording medium of phase change type which the main components of the recording layer are Sb and Te and the production method of the optical information recording medium which has the characteristic of introducing charged particles to the sputter room at the time of the start DC(Direct Current) spatter of the recording layer. (2) A discharge trigger device used for a sputter device for optical information recording medium production consisting of an electron introducing means to introduce electrons generated by a charged particle generation means and the charged particle generation means to the sputter room. (3) The production device of the optical information recording medium of the phase change type which the main components of the recording layer are Sb and Te and the production device of the optical information recording medium which has the characteristic of arranging the discharge trigger device described in (2) next to the DC sputter room of the recording layer.
