Abstract: PURPOSE:To make the designating operation of a track number for which no direct music selection key is provided, simpler and easily understandable. CONSTITUTION:In the recording/reproducing device corresponding to a recording medium having, for example, 255 manageable tracks, direct music selecting keys '1' to '25' and a track designating key '>25' used for designating the 26th and after 26th tracks are provided as inputting means. A control means is constituted in such a way that, when one of the direct music selecting keys is operated, the control means discriminates that the track corresponding to the numeric value of the operated key is inputted and, when the track designating key is operated, discriminates that the tracks corresponding to numeric values obtained when the values of numeric keys are arranged in the operating order of the direct music selecting keys repetitively operated a plurality of times.

Abstract: PURPOSE:To handle general digital data by the digital audio recording and reproducing device without increasing the size. CONSTITUTION:When digital audio data are recorded, the digital audio data are recorded on a recording medium 1 through an input connector 31, a 1st interface circuit 32, and a recording and reproducing means 4. When the digital audio data are reproduced, the digital audio data are outputted to an output connector 34 through the recording medium 1, recording and reproducing means 3, and interface circuit 32. When the general digital data are recorded, the digital data are recorded on the recording medium 1 through the input connector 31, a 2nd interface circuit 35, and the recording and reproducing means 4. When the digital data are reproduced, the digital data are outputted to the output connector through the recording medium 1, recording and reproducing means 3, and 2nd interface circuit 35.

Abstract: PURPOSE:To improve the reading easiness of a displayed character by performing a conversion display into a second character kind on the side of a reproducing device as necessary for a medium where character information is recorded by a first character in a prescribed area. CONSTITUTION:In an optical magnetic disk 1, character information is recorded by an ASCII code. This is read by a system controller 11 and is displayed on a display part 20. At this time, a KANA (Japanese syllabary) conversion part 21 converts the character in a Roman character form by the ASCII code into a the KANA (Japanese syllabary) for the character information to be outputted as display data from the controller 11 to the display part 20. In a switching part 22, the character information by the ASCII code is switched by selecting whether the information is supplied as it is to the display part 20 and is displayed or it is converted in a conversion part 21 and a Japanese syllabary display is performed for it. The conversion part 21 and the switching part 22 are composed of the software means in a controller 11.

Abstract: PURPOSE:To reduce the installing area of a memory and to reduce the cost and also to miniaturize the device by processing data by storing recording data and an error flag relative to the recording data into one memory. CONSTITUTION:A sound data recording area 40 and an error flag recording area 41 are provided in a recording area of a RAM 6, and a residual amt. of a vacant area of the area 40 is calculated by a memory residual amt. calculator 22. Then, write and read of the error flag is controlled by an error flag address calculated by an error flag address generator 24 based on the residual amt. of the vacant area and the recording state of the sound data in the area 40. By this method, the RAM to write and read the sound data can be used in common as a RAM to write and read the error flag, so that the installing area can be reduced and the device can be miniaturized.

Abstract: PURPOSE:To reduce an installation area of plural RAMs and to reduce the cost and the size of the device. CONSTITUTION:Storage areas of a RAM 6 are divided into plural storage areas and a RAM controlling circuit 8 controls the writings and the readings of voice data, TOC data, error flags and subdata into these plural storage areas. Thus, there is no need to provide respective dedicated plural RAMs and plural kinds of data writing and reading are performed to a single RAM.

Abstract: PURPOSE:To continuously record a data in a recording track by providing a memory means for reading an input data as a recorded data, a recording means and a control means for controlling the recording position in the recording track. CONSTITUTION:A memory 14 is controlled on the write and read of data by a system controller 7, and a data is continuously written at a constant transfer speed. When the data amt. exceeds a prescribed amt., an increment of a read pointer of the memory 14 takes place in a burst-like mode, and the memory is controlled to be read out. The read recorded data is supplied to an encoder 15. By this method, an input data can be recorded under its continuous state on a recording track of a discoid recording medium.
