Method for optical information recording

ABSTRACT A method for erasing and recording information on an optical recording member of the type wherein a new signal is overwritten on a previously recorded track by means of a single laser spot passing only once thereon. The method comprises the steps of modulating a recording laser power to a recording power level (PW): maintaining the laser power at the recording power level (PW) for a time corresponding to data to be recorded: lowering the laser power to a cooling power level (PC) which is lower than the recording power level (PW); and maintaining the laser power level at the cooling power level (PC) for a predetermined period, to thereby record information. By modulating the recording laser power at three power levels, the irradiation power becomes small immediately after the recording power level and thus the irradiated parts can be cooled quickly. Therefore, a large amorphous area can be formed or a large difference between complex refractive indexes can be obtained, since the microcrystals are hardly included in the recording part, and the complex refractive index of the recording bit becomes small. Therefore, a large reproduced signal is obtainable.

To an area between the second marks is applied the light beam after having been modified to have a reduced energy to cause the area to melt and become a state substantially identical to the second state, whereby the record marks can be read highly reliably. In another aspect, each record mark is formed in a symmetrical shape by application of a train of light pulses providing an energy gradually reduced from the beginning to the ending of the predetermined duration.

When a flash light irradiates, a part of incident light which obliquely enters into an inner and an outer periphery regions of the optical recording medium is shaded by the walls. A quantity of the incident light incident on a unit area in each of the inner and outer periphery regions is less than that in a recording region between the inner and outer periphery regions. When temperature in the recording region reaches to an initializing temperature, the temperature in each of the inner and outer periphery regions is lower than the initializing temperature. So that neither cracks nor corrugations occur in a recording layer in the inner and outer regions.
