An optical recording method for recording mark length-modulated information on a recording medium by using a plurality of recording mark lengths. The optical recording method comprises the steps of: when a time length of one recording mark is denoted nT (T is a reference clock period equal to or less than 25 ns, and n is a natural number equal to or more than 2), (i) dividing the time length of the recording mark nT into eta1T, alpha1T, beta1T, alpha2T, beta2T, ..., alpha1T, beta1T, ..., alphamT, betamT, eta2T in that order (m is a pulse division number; Sigmai(alphai+betai)+eta1+eta2=n; alphai(1 <= i <= m) is a real number > 0; betai (1 <= i <= m-1) is a real number > 0; betam is a real number >= 0; and eta1 is a real number of -2 <= eta1 <= 2 and eta2 is a real number of -2 <= eta2 <= 2); radiating recording light with a recording power Pwi in a time duration of alphaiT(1 <= i <= m), and radiating recording light with a bias power Pbi in a time duration of betaiT(1 <= i <= m), the bias power being Pbi < Pwi and Pbi < Pwi+1; and (ii) changing m, alphai, betai, eta1, eta2, Pwi and Pbi according to n of the time length nT of the recording mark; wherein the pulse division number m is 2 or more for the time duration of at least one recording mark and meets n/m >= 1.25 for the time length of all the recording marks.
