PORTABLE DEVICE FOR RECORDING AND PLAYING DISK

摘要

PURPOSE: A portable device for recording and playing a disk is provided to reduce the size of a player by using a small disk, thereby conveniently carrying out the player and easily exchanging the disk. CONSTITUTION: A data transmitting and receiving unit(11) transmits and receives general data to and from an external data processor. A coding and decoding unit(13) encodes the data inputted from the data transmitting and receiving unit or decodes the played data. A transmitting unit(14) controls the coded data for transmitting the coded data in the case that power source is supplied. A pick-up(15) records the data inputted from the transmitting unit on a disk(17) or reads the data recorded on the disk for converting the same into electric signals. A receiving unit(16) amplifies and filters the converted electronic signals and converts the electronic signals into a form easily extracting data. An audio input and output unit(12) receives the decoded audio data for converting the same into analog audio signals to be output to an external device, and coverts the analog audio signals inputted from the external device into digital data to be transmitted to the coding and decoding unit. A diameter of the disk is less than 8 cm.
