    摘要： The present invention provides a recording medium (10) having a plurality of charge accumulating regions (14) each containing a first material capable of accumulating an electric charge and a photoconductive region (17) containing a second material whose conductivity is increased by light absorption, a recording apparatus including such a recording medium (10), and a method recording information on such a recording medium (10). In the present invention, information is recorded on the recording medium (10) by irradiating the photoconductive region (17) with light and by injecting an electric charge into the charge accumulating region (14) via that portion of the photoconductive region (17) which is irradiated with light.

    摘要： The unit comprises a storage medium (6) supported on a mechanically stable substrate (5), a read/write arrangement (7...17e) employing a plurality of laser light sources (8a...8f) and an interrogation light source (3). The laser light source are designed as laser diodes (8a...8f) attached to a substrate (7) and optically aligned with an equal plurality of microlenses (12) integrated in a first transparent layer (11). The read/write arrangement (7...17e) further comprises at least one second transparent layer (13,14), and an optional semitransparent conductive coating (16), said layer or said coating (16) carrying a plurality of particulate protrusions (17a...17d) which are also aligned with said diodes (8a...8d) and said microlenses (12), said storage medium (6) and said read/write arrangement (7...17e) being maintained in a mutually parallel alignment with a gap in between having a width of less than 100 nm.
    The method involves the following steps for writing information:

    mutually parallel displacing the surfaes of said/write arrangement (7...17e) and of said storage medium (6) in order to align a selected one of said particulate protrusions (17a, 17d, 17e) with a selected bit location within the associated bit cell,
    decreasing the distance between said read/write arrangement (7...17e) and said storage medium (6) so that the said particulate protrusions (17) exert pressure onto the storage medium (6)
    energizing the diode (8a, 8d, 8e) associated with the selected protrusion (17a, 17d, 17e) so as to heat up selected protrusion to a temperature at which the material of said storage medium (6) starts flowing, in order to emboss a dint (18a, 18d, 18e) into the storage medium (6).
    deenergizing said selected diode (8a, 8d, 8e) and increasing the width of the gap (15), thereby removing the impact of said protrusions (17) from said storage medium (6) and permitting the latter to cool, thus reserving said dint (18a, 18d, 18e).

    The method further involves the following steps for reading information:

    mutually parallel displacing the surfaces of said read/write arrangement (7...17e) and of said storage medium (6) in order to align a selected one of said particulate protrusions (17a, 17d, 17e) with the bit location within the associated bit cell from which information is to be read,
    activating said interrogation light source (3) to cause a light wave to travel along said light waveguide (6, 14, 15, 16) said light wave being particularly scattered at said dint (18a, 18d, 18e) representing the stored information and illuminating the diode (8a, 8d, 8e) associated with said dint (18a, 18d, 18e), said diode (8a, 8d, 8e) generating an electric output signal representative of the information read.
