During the last five years, the surface resistance R s (10 GHs, 77 K) of YBCO thin films has decreased from a value of about 10 to 20 milliohms-i.e. the same as cooled pure copper or as bulk YBCO-down to values lower than 200 micro-ohms, close to the

The concept of stationary head digital recording has been pushed forwards in the audio domain (S-DAT, DCC). However conventional thin film head technology limits the track density to 500 TPI. We have developed a new head design which allows head stac

The following new components have been developed for magnetic tape recording: the matrix writing head, which allows fine track pitch and high integration (1,024 tracks) at reasonable cost, and the Kerr reading head, which takes advantage of optics fo

Magnetic tape has a potential storage density quite comparable to that of optical media. Furthermore it takes advantage of a long history of industrial development leading to low price high quality and availability. Tests on commercial VTR showed tha

Magnetic tape offers potential capacities of 20 Mbits/cm2, while conventional readout heads are limited, particularly by the impossibility of integrating a large number of heads in a stack. A magneto-optical high resolution transducer, using thin gar
