摘要：Disclosed is a method of recording/reproducing information signals at an access

speed in the order of &mgr;s, a recording density of 1 to 10 GBs/cm, and a data transferrate in the order of Gbit/sec without breakage of the data. The method includes thesteps 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 eachof which has at its leading end a flat portion having an area of 0.1 &mgr;mor less; movingthe head device relative to the memory medium a distance more than a gap between twoadjacent ones of the head elements; and recording an information signal at a specificposition of the recording surface at a recording density of 1 Gbit/cmor more, orreproducing an information signal previously recorded on the recording surface at aspecific position by the head device.
