Record member for magnetic and optical recording

A record member comprising:

• a thin sheet of recording material having a rectangular shape with opposite paralle straight edges,
• a central portion of said record member being rectangular in shape and containing a plurality of closely spaced parallel record tracks, with information being recorded along at least some of the parallel first record tracks,
• a first strip-like portion of said record member extending adjacent one edge of, and outside of, said rectangular central portion containing said parallel record tracks, said first strip-like portion including a plurality of first parallel code recordings,
• each of said first code recordings being aligned with a respective one of said parallel record tracks so as to respectively indicate the locations of selected ones of said record tracks, for permitting individual selection and reading of information from said record tracks, and
• a second strip-like portion of said record member extending adjacent an opposite edge from said one edge of, and outside of, said rectangular central portion, said second strip-like portion including a plurality of second parallel code recordings, identical to said first parallel code recordings in position and informational content, relative to said record tracks, respectively, the combination of said first and second parallel code recordings providing alignment coding means for orienting said record member on a receiving member.

A record member for information storage and use with transducing means for reproducing information stored thereon comprising:

• a thin sheet of electro-optical recording material;
• a coating of magnetic recording material covering said thin sheet;
• a central portion of said record member containing a plurality of closely spaced parallel record tracks with information recordings extending along at least certain of said parallel record tracks, said record tracks being receptive of of optical and magnetic recording of data;
• first and second strip-like portions of said record member extending parallel opposite edges of and outside said rectangular central portion, said first and second strip-like portions each having a plurality of parallel optical code recordings extending therealong, each of said code recordings being identically aligned with a respective one of said parallel record tracks,
• said code recordings each including first bit codes defining respective locations of said parallel record tracks of said record member, for providing coding means for both selecting a given record track and relatively aligning said record member and said transducing means.
