An optical recording carrier for recording and/or reading information by irradiation with light comprises a conductive material layer capable of being electrostatically charged. An optical card comprises a recording layer and a substrate, wherein said optical card has a conductive material layer capable of being electrostatically charged. A recording and/or reading apparatus employing an optical recording carrier or an optical card comprises a means for keeping electrostatically charged a plate constituting an optical recording carrier or optical card holder of which an optical recording carrier or optical card having a conductive material layer capable of being electrostatically charged is placed, to attract said optical recording carrier or optical card to said optical recording carrier or optical card holder by Coulomb's power, and a means for driving said optical recording carrier or optical card. A recording and/or reading process employing an optical recording carrier or an optical card comprises keeping electrostatically charged in mutually opposite polarity, both of an optical recording or optical card having a conductive material layer capable of being electrostatically charged and a plate constituting an optical recording carrier or optical card holder of a recording and/or reproducing apparatus, to attract said optical recording carrier or optical card to said optical recording carrier or optical card holder in close contact, and effecting irradiation with light under this state to carry out the recording and/or reading.
An optical recording carrier comprising an optical recording layer adapted to be irradiated with light for recording information thereon or reading information therefrom, and a conductive material layer capable of being electrostatically charged for generating electrostatic force between said optical recording carrier and a recording and/or reading apparatus.
An optical card comprising a optical recording layer adapted to be irradiated with light for recording information thereon or reading information therefrom a substrate, and a conductive material layer capable of being electrostatically charged for generating an electrostatic force between said optical card and a recording and/or reading apparatus.
