    摘要: An optical recording element comprising a recording medium which includes an information recording area formed at every unit in a non-continuous condition, the recording medium further including sample pits disposed at intervals of a fixed distance for providing basic information about the locations of the recording units in same track. Each sample pit comprises a plurality of pits disposed next to the sequence of the recording units so that the spacing between the pits differs from the spacing between the recording units. At least one of the plurality of pits is a long-sized inclined pit which is inclined at an angle in the range of 6.degree. to 80.degree. to a recording track. A driving system for driving the optical recording element for recording information in the non-continuous recording area or erasing information stored therein with a light beam the output of which is varied as required and checking whether said recording or erasing has been correctly performed, within a very short time in which the light beam passes through the non-continuous recording area. By using the optical recording element in combination with its driving system, the processing speed for reducing, erasing and verifying these functions can be greatly improved and the irradiating position of the light beam at every recording unit can be correctly controlled.

    摘要: A photo-mask for use in manufacturing an optical memory disc has a substrate having a disc shape and made of a transparent material, and a film deposited on the substrate and formed with a predetermined pattern of grooves extending spirally or concentrically to the center of the disc shaped substrate such as to leave a thin film at the bottom of the grooves, and a number of microscopic pits in the form of minute indentations with a predetermined spacing aligned along the grooves so as to substantially leave no film at the bottom of the indentations. Thus, a light which has passed through the thin film at grooves is weakened and a light which has passed through the indentations loses substantially no power, and a light applied elsewhere on the film is cut off. The photo-mask is made through the steps of depositing an opaque film on a substrate having a disc shape and made of a transparent material, impinging a first laser at places where the grooves are to be formed, and impinging a second laser at places where the pits are to be formed. The first laser is weaker in power than the second laser.
