Very flexible Co-Cr/Ni-Fe bilayered tape media have been prepared. Total thickness of magnetic layer reduced to value as small as 0.33 μm. 0.20 μm thick Ni-Fe layer and 0.13 μm thick Co-Cr one were deposited on 10 μm thick polyimide long sheet as a substrate using a roll ...
Magnetic Tape Sound Recording And Reproducing Systems - Methods For Measuring The Mechanical Characteristics Of Magnetic Tape For Analogue RecordingBritish Standards Institution
CONSTITUTION:A test signal is recorded and then reproduced, and on the basis of the state of the reproduced signal, the best operation characteristics of recording, reproduction, or recording and reproduction which correspond to the magnetic characteristics of a magnetic tape to be used are set ...

The effect of NbBaddition on the critical current density in applied magnetic fields (J-B characteristics) of iron sheathed MgBtapes prepared via an in situ powder-in-tube (PIT) technique was investigated. The results show that the J-B characteristics of MgBtapes are enhanced by the addition ...
Critical currents of powder-in-tube processed silver-clad Bi-2223 short tape samples and coils have been measured at liquid nitrogen (77 K), liquid neon (27 K), and liquid helium (4.2 K) temperatures. The short samples have been characterized in fields up to 20 T and indicate a large ...
Voltage-current characteristics at four different applied magnetic fields (7, 20, 30, and 40 mT) of Bi2Sr2Ca2Cu3Ox superconducting tape were measured in the temperature range from 100 to 115 K. They were also measured at zero magnetic field before and after irradiations up to 10 MRad at ...
The structure allows for simple and easy measurement of magnetization characteristics of magnetic thin films attached to a magnetic printing, magnetic tape, etc. by simply setting the magnetic thin film at a position. The result of the measurement is displayed on a display screen or indicated ...
