Application March 1 Claim.
This invention relates toa postcard for phonographic recording, which is made by pasting to the ground paper of postcard size a thin aiuminum oxide sheet obtained by oxidizing the surface of a thin aluminum sheet by so-cailed anode treatment. The object thereof is to obtain a postcard for phonographic recording which enables a correspondent to record his voice or a piece o! music on it besides writing his business.
The known phonograph record of postcard type is made by pasting a celluloid sheet with a sound previously recorded to the ground paper, so it is impossible to use it for a communication purpose by recording a message. Now, this invention is postcard for phonographic recording made by pasting to the ground paper oi postcard size a thin aluminurnoxide sheet obtained by oxidizing the surface of a thin aluminum sheet by so-called anode treatment. According to this invention unlike the knownpostcard of this type, it is possible to record ones own voice and also write amessage.
Referring to the accompanying drawing,
' Figure 1 is a plan of the postcard for phonographic recording according to this invention, partly broken away, and
Tokyo, Japan Figure 2, an enlarged sectional view of the same.
In the drawing, a thin aluminum oxide sheet i obtained by oxidizing the surface oi a thin aluminum sheet by so-cailed anode treatment is pasted 2 oi postcard size and then is pierced with a round hole 3 in which to insert the rotatable shaft of a phonograph. In this invention, if letters are written in ink on the aluminum oxide sheet pasted to the ground paper, beautiful lustre and will not be wiped out even with a wet cloth, Moreover, as an aluminum oxide sheet has very ideal hardness for recording a sound with a needle which has diamond at its point and also for reproducing such a sound with a steel needle, it has the practical advantage oi enabling a correspondent to record his voice or a. piece oi music on it besides writing his business.
Having thus described my invention, what I claim is:
A postcard for phonographic recording, comprising a paper base of postcard size and thickness, and a thin aluminum sheet secured on said y base and having an aluminum oxide iilm on its surface.
