ABSTRACT:
There is described, among other things, an accessory for a phonograph record disc which has a center hole axially of a label portion of the disc. The accessory comprises a sheet which is of circular annular shape and has a diameter not substantially greater than the disc label portion. One side of the sheet carries adhesive for affixing the sheet to the label portion of the record concentric to its center hole. The opposite side of the sheet carries an annular band which is positioned concentric to the center of the sheet. The annular band is defined by a magnetic recording medium. The magnetic recording medium facilitates the placement of information on the record disc which can be read and used by a programmable record player.
The invention also describes a phonograph record having a central label portion and a circular hole through its axis. The record includes a band of magnetic recording medium affixed to the label portion concentric to the hole.
