Abstract
A solid-state memory concept is discussed, featuring a removable data carrier on which information is stored in a pattern of magnetic bits. The information is read out with a sensor array of magnetic tunnel junctions. The calculated readout signals of the sensors are compared with the measured values for a magnetic card with a data density of 0.5 Mbyte ∕ cm 2 . The card-sensor separation is identified to determine the ultimate achievable data density.Keywords
