TW470940B - Digital tape for sound recording and playing - Google Patents

Abstract

The invention provides a digital tape for sound recording and playing, primarily including a CPU, recording unit, memory unit, inspection unit, decompression unit, analog unit, magnetic sensing playing unit and so on. When playing, the memory unit provides data to CPU and CPU receives the command from the inspection unit to be converted via the analog unit so that the output can go through the sensing output of the magnetic sensing playing unit or headset. When recording, it can go through recording unit to input data or go through USB interface unit to link the relevant computer and download data, or go through CCD camera unit to input pictures for further being saved in memory unit after being compressed by CPU. The display can go through the display unit of the connected analog unit and the sending/receiving can go through the infrared receiving unit of the CPU to receive the data transmitted from another cassette or transmit data to said cassette by means of the cassette in connection with the infrared transmission unit of the decompression unit or achieve fast data exchange of two cassettes by means of serially connecting the male and female USB interfaces.
