    摘要： A method for recording information is disclosed in which an information recording medium is irradiated with a recording energy beam power-modulated into at least a record power level and a record-ready power level lower than the record power level. When forming a mark portion of a predetermined length, the radiation energy of the energy beam is increased as compared with when forming a mark portion of a different length before or after the first pulse of an energy beam pulse train including at least a pulse for forming the mark portion. Also, only in the case where the energy beam is modulated by the power lower in power level than the record-ready power level after the last pulse of the energy beam pulse train including at least one pulse for forming a mark portion and the mark portion is followed by a space portion of a predetermined length, the particular radiation energy of low power level is reduced as compared with when the mark portion is followed by a space potion of a different length. The radiation energy is increased and/or decreased.

    摘要： In an apparatus for measuring texture and characterization of the surface of a sample on the basis of the drive signal of a servo control circuit by allowing a probe-tip (1) to approach the sample (2) and subjecting the probe-tip (1) to servo control so that a current, which is generated by moving the probe-tip (1) on the sample surface and which flows between the probe-tip (1) and the sample (2), becomes constant, the present invention discloses a surface metrological apparatus comprising a circuit (11, 12) for correcting the texture and characterization of the sample by use of a current error of the measured value of the current described above from the set current value.

    摘要： In a storage apparatus wherein signals recorded on tracks assigned addresses in advance on a rotary recording medium such as an optical video disk are randomly searched at high speed, a random access storage apparatus is provided in which erroneous searches attributed to a transient phenomenon due to a jump for the search, a drop-out, etc. are prevented.The storage apparatus includes an error check circuit. In a random access operation, a read head is mechanically moved to the vicinity of a target address, whereupon an address signal of a track to which the head has been moved is read. Whether or not the address signal is normal is determined by the error check circuit. If the address signal is determined to be normal, it is stored in a register as a reference address. A light spot is deflected by the number of tracks which corresponds to the address difference between the reference address of the register and the target address.If the address signal is determined to be abnormal, the light spot is unconditionally deflected onto the adjacent track and an address signal is read out at the new position of deflection. Thereafter, the error decision and the subsequent operation described above are carried out.
