Abstract

PURPOSE:To obviate a decrease in yield and to widen the width for the adjustment of an adhesive agent so that a recording medium can be easily produced by forming the recording medium in such a manner that a stuck surface has partly recesses lower than said surface or has the recesses facing the surface. CONSTITUTION:The stuck surface 4 has partly the recesses 1, 2 lower than the surface 4 or the recesses facing the surfaces 4. The recesses 1, 2 function to prevent the bleeding of the excess adhesive agent, etc., cast by rolling of the surface 4 to the end face or inside space surface of the recording medium. The excess adhesive agent, etc., are thus accumulated into the recesses 1, 2. The permissible amt. of the adhesive agent to be used for the sticking is thereby increased and the control of the amt. of the adhesive agent is facilitated; in addition, the generation of a defect by bleeding of the adhesive agent, etc., as the recording medium is decreased.
