ABSTRACT:
A multi-track magnetic recording head is used to record data in human readable form on a magnetic track on a record medium. A viewer, having a viewing window containing microencapsulated ferromagnetic particles, is used to read the data. When the viewing window is placed in operative proximity with the magnetic track, an image corresponding to the data on the track is formed on the viewing window to enable a user of the record medium to read the data thereon. The image on the viewing window is erased after reading by providing relative movement between the viewing window and a magnetic field.
