To provide a recording method and a recording medium to obtain satisfactory reproducing characteristics by providing a specifically laminated relation among a recording pit width, a guide groove width of a transparent substrate and a guide groove pitch of the transparent substrate, in a high speed optical recording method and an optical recording medium.

In the optical recording medium having a recording layer, a reflection layer and a protective layer on the transparent substrate, the optical recording method characterized in that a recording pit is irradiated with recording light and formed so that the following formulae are satisfied is adopted as a principal constitution. -0.2p≤d-a≤0.2p wherein d=d+m wherein p: the guide groove pitch of the transparent substrate a; the guide groove width of the transparent substrate d; the recording pith width k; substrate deterioration part width m; recording layer deterioration part width.
