ABSTRACT

A system and method for recording audio messages on a paper fixed with magnetic tape strips and read and playback functionality for the recorded messages using an improved mobile phone is provided.  Further, the system and method provides security encryption of the recorded audio messages and sending the encryption keys over the air to another mobile phone for decrypting and reading the audio message correctly. 

PROBLEM

The present newspaper printed in paper carries only text and pictures and not voice.  People have to look for other sources like TV, radio or download the voice to their mobile to listen the voice which is an unnecessary effort.

Presently audio messages cannot be written to and read from a medium like paper directly.

 

There are devices which use text-to-speech synthesis for scanning a text and then convert to voice.  But they cannot generate the voice as generated by humans.  Speaker identification is impossible from such machines.

So, what is needed is therefore a system for recording an audio message uttered by human or other voices in a paper medium preferably with a device which is used widely and daily by general public.  Further, such a device should have a playback of the audio message from the paper medium maintaining the qualities and characteristics of the original message.  Further, such a method is desirable to have security encryption to enable playback only by authorized users.

SOLUTION

CDMA mobile phone uses different mechanisms of channel coding to reduce the error when the signal is transmitted over air.

Most of the signal processing capabilities of the mobile phone is used with integrated additional hardware to make it function like a paper tape recording and reading system.

OPERATION

According the invention a mobile phone is provided with a magnetic head for reading and writing, roller for controlling the speed of writing and “RED” and “GREEN” LEDs for guiding the user to show whether the speed at which he moves the mobile over the strip crossed the maximum speed limit.  Figure 1 captures the paper and the mobile phone used as audio reading or writing.

THE MAGNETIC TAPE ON PAPER

The tape consists of a thin plastic base material with a coating of ferric oxide powder. The oxide is normally mixed with a binder to attach it to the plastic, and it also includes some sort of dry lubricant to avoid wearing out the recorder.  This magnetic tape which is usually very thin is pasted on any writing paper or newspaper as strips as shown in Figure 1.  Usually the width of the magnetic strip is 0.125 inches.  The present cassette’s tape can be pasted on a paper or tape with paper can be produced and made commercially available.  This forms the medium of writing for the paper tape recorder and reader system of the present invention.
