Abstract
An information recording and reproducing apparatus which has a memory portion which uses the Bloch lines occurring at the magnetic domain walls at the periphery of magnetic domains present in magnetic garnet films as the information carrier, a drive portion to write information into or read information from the said memory portion, and in which the memory portion is constructed to be connectable to and disconnectable from the drive means, wherein the signal transfer is carried out via a connection means when the said memory portion is set in the drive portion. In this information recording and reproducing apparatus, since the recording portion can be freely connected to or disconnected from the drive portion, it is possible to selectively insert portable substrates storing different information in the same apparatus body portion.
