Abstract: A method for overwriting information in a magneto-optical memory medium which comprises a substrate (11) having a layer of magneto-optical recording material (13) with a perpendicular magnetising characteristic coated on it. The method includes applying a write signal (W) in the form of a pulsed laser beam having a power sufficient to write information into an information-carrying area of the memory medium and applying an erase signal (E) in the form of a laser beam having a power lower than the write signal (W), insufficient to write information into the memory medium but sufficient to erase any information previously written into the information carrying area of the memory medium. Either the write signal (W) or the erase signal is applied over all of the information carrying area of the memory medium to be overwritten regardless of the previously written information. A single laser beam head (21) may apply either the writing signal (W) or the erase signal (E) selectively in accordance with the information to be written onto the information carrying area of the memory medium. Alternatively, initially the erase signal is applied to the information area of the memory medium to be overwritten to erase information previously written on it, and then the write signal is selectively applied to the information area to write the required information into the ifnormation area of the memory medium.

Abstract: A method and apparatus for reducing noise in a light sensing circuit having a photodiode array (80) coupled to a charge amplifier (85) through a field effect transistor transfer switch (116). Thermal noise generated by the transfer switch (116) is combined with image signals inputted to the charge amplifier (85) resulting in an outputted noisy image signal. The invention eliminates this noise by taking two consecutive readings of the charge amplifier output, one before and one after closing the transfer switch (116) and after opening it. The thermal noise generated by the transfer switch (116), and added to the next reading of the charge amplifier output, is equal to the difference between these two readings. Once stored, this difference can be subtracted from the previously mentioned "next reading", resulting in the elimination of this noise term.
