<p>The invention relates to a strip-shaped security magnetic recording support. It comprises a support (I bis) covered with a continuous magnetic layer (2) and with thickenings (3) integral with the support (2), the magnetic media being constituted by magnetisable particles having a substantially identical coercive field, the thickenings having a thickness greater than 40% of the average thickness of the continuous magnetic layer. The support (I) is fabricated preferably by hot transfer processes under pressure. Application of the support to authentication or discrimination of an object comprising the said magnetic support by electromagnetic means. <IMAGE></p> |
