Method of recording/reproducing an information signal
First Claim
1. A method of recording/reproducing an information signal, comprising the steps of:
- making a head device face to a memory medium having a flat recording surface, said head device including a plurality of head elements two-dimensionally arranged each of which has at its leading end a flat portion having an area of 0.1 μ
m2 or less;
moving said head device relative to said memory medium a distance more than a gap between two adjacent ones of said head elements;
and recording an information signal at a specific position of said recording surface at a recording density of 1 Gbit/cm2 or more, or reproducing an information signal previously recorded on said recording surface at a specific position by said head device.

Abstract
Disclosed is a method of recording/reproducing information signals at an access speed in the order of μs, a recording density of 1 to 10 GBs/cm2, and a data transfer rate in the order of Gbit/sec without breakage of the data. The method includes the steps of: making a head device face to a memory medium having a flat recording surface, the head device including a plurality of head elements two-dimensionally arranged each of which has at its leading end a flat portion having an area of 0.1 μm2 or less; moving the head device relative to the memory medium a distance more than a gap between two adjacent ones of the head elements; and recording an information signal at a specific position of the recording surface at a recording density of 1 Gbit/cm2 or more, or reproducing an information signal previously recorded on the recording surface at a specific position by the head device.
