A magnetic recording medium (12) and a magnetic recording apparatus (10) that makes use of the magnetic recording medium is disclosed. The magnetic recording medium includes an elongated magnetic base film that is significantly thicker than conventional magnetic tape and that presents opposed front (20) and rear faces (22) and opposed upper (24) and lower edges (26) extending between the front and rear faces. One or more layers of magnetic material is coated on both the front face and on the upper edge of the base film. Data is recorded on the front face of the base film in a conventional manner, and sequencing or locating information is recorded on the upper edge of the base film. This permits a read/write head (18) to hover over the base film to read the sequencing information on the upper edge of the base film for locating the position of desired data stored on the front face of the base film. Once the desired portion of the base film is located, the read/write head is plunged or lowered adjacent the front face of the base film to read the desired data from and/or write data to the base film.
