Abstract
Provision of a highly reliable magnetic recording medium with able to record further high density recording, usable advantageously as a magnetic tape for recording computer data, and having a further improved SNR, and a method for reproducing signals magnetically recorded on a magnetic recording medium to reproduce more desirably magnetic recording such as computer data with high density recording or the like. The magnetic recording medium having, on either side of a flexible nonmagnetic support, a nonmagnetic layer containing a nonmagnetic powder and a binder, and a magnetic layer containing a ferromagnetic powder and a binder, having a thickness in the range of from 0.2 to 0.6 &mgr;m in this order, where a laminated head is used for reproduction. The method for reproducing signals magnetically recorded medium having, on either side of a flexible nonmagnetic support, a nonmagnetic layer containing a nonmagnetic powder and a binder, and a magnetic layer, with a thickness ranging from 0.2 to 0.6 &mgr;m, containing a ferromagnetic powder and a binder in this order, where a laminated head is used as a reproducing head.
