Abstract:
A method of recording/reproducing an information signal, in which an information signal is reproduced from a flat memory medium on which information is two-dimensionally arranged and recorded, by moving a head element, arranged to be opposed to and in parallel to the information signal recording surface of said memory medium, relative to said memory medium, comprising the steps of:two-dimensionally sampling a reproducing signal at an interval being a half or less of a pitch between signals two-dimensionally arranged on said memory medium;temporarily storing a specific amount of the data in a buffer memory;identifying, from said reproducing signal, an address signal as two-dimensional positional information stored on said memory medium; andsignal-processing a time at which the address signal is reproduced, a relative speed between said head element and said memory medium, a relative moving direction between said head element and said memory medium, and a data row stored in said buffer memory, thereby decoding the content of the data at a specific position on said memory medium.
