Abstract: PROBLEM TO BE SOLVED: To provide a recording and reproducing device and a recording and reproducing method by which both of the track name and the next are recorded by automatically copying the track name or the text to the text or the track name as to an optical disk where only either of the track name or the text of audio data is recorded. SOLUTION: The recording and reproducing device is provided with a microcomputer 13 that discriminates whether a track name of audio data or a text is recorded and generates one on the basis of the other when one of them is recorded, a memory control circuit 10, and a RAM 11 and records the generated track name or text onto an optical disk 20. Thus, the track name or the text is automatically generated to an optical disk to which the text or the track name is not recorded so as to save the trouble of data entry.

Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which an economical burden is reduced by a method wherein auxiliary data is read out from a copy source disk, so as to be stored in a storage region and the auxiliary data is recorded, from the storage region, in a copy destination disk, which is loaded after the copy source disk is discharged. SOLUTION: Auxiliary data on a static image or the like which becomes an auxiliary data file which is independent of data on a piece of music or the like as a program is recorded in copy source disk 90, in addition to the data on the piece of music. As the recording region of the auxiliary data, 38 clusters are prepared inside a U-TOC, and the auxiliary data is JPEC- compressed and recorded here. When the copy source disk 90 is placed, a system controller 11 reads out the auxiliary data so as to be retained in a buffer memory RAM 13. After the copying operation of the auxiliary data is instructed, the copy source disk 90 is replaced by a new disk to be copied. Then, the system controller extracts desired data from the data in the RAM 13, and the data is recorded in a space area inside the U-TOC on the copy source disk 90, which is placed at present.

Abstract: PROBLEM TO BE SOLVED: To simultaneously record speech information and character information onto a recording medium and allow a user to obtain an appropriate editing operation condition based on one's own preference and judgment by including a broadcast speech signal and the character information in a recording unit format to be continuously recorded on a disk. SOLUTION: For a recording medium having a recording unit format which includes speech data and sub-data, a recording data stream is generated while using a broadcast speech signal and character information as the speech data and the sub-data of the recording unit format, respectively, to perform the recording. Thus, both the broadcast speech signal and the character information can be simultaneously recorded onto the recording medium without any difficulty in terms of time/timing or capacity for the recording operation. Furthermore, it becomes possible to simultaneously reproduce the broadcast speech signal and the character information at the reproduction. Thus, it becomes possible for a user to perform an appropriate editing operation and a timer recording which is mainly intended for the character information.

Abstract: PROBLEM TO BE SOLVED: To optimally set rotational speed in a disk device which makes rotation control by the CAV (constant angular velocity) system. SOLUTION: A MD 1 on which data is recorded by the CLV(constant linear velocity) system is divided into plural regions in the diametrical direction and for each of these regions a rotational number enlarged toward the inner peripheral side is set. Divided regions, address information corresponding to these regions and the rotational numbers corresponding to the regions are set in advance as table information. The outermost shell record position is determined based on the end address information of sector zero of the U-TOC(User TOC) read from the MD 1. With reference to the table information, which region the record position of the outermost shell belongs to is judged and the corresponding rotational number is determined. The rotation of a motor 2 is controlled by the CAV system based on this number of rotation. Since data is adaptively set in accordance with the recorded region, high-speed disk drive is enabled. And in intermittent readout, further saving of power consumption is made possible.

Abstract: PURPOSE: To realize quick access operation by inhibiting the execution of operation control for reducing power consumption by a power-saving mode control means in the case where power is supplied by using an external power source. CONSTITUTION: A reproduced RF signal is processed by decoding-processing such as EFM demodulation and CIRC, etc., by an encoder/decoder part 8, and is sent to a data primary storage part 40, and is written once in a RAM 13 by a memory controller 12. The transfer of reproduced data in a data writing-in/ reading-out part 30 is executed intermittently at 1.4Mbit/sec. The data written in the RAM 13 is read out at timing where the transfer of the reproduced data becomes 0.3Mbit/sec, and is sent to a recorded/reproduced signal processing part 50, and is supplied to the encoder/decoder part 14. Then, it is given reproduced signal processing such as decoding processing, etc., for sound compression processing, and is turned into an analog signal by a D/A converting part 15, and is supplied to a prescribed amplifier circuit from a terminal 16, and is reproduced and outputted.

Abstract: PURPOSE:To improve the operability for registration of character data which can be recorded corresponding to main data by making it possible to input and store in advance the character data to and in a storage means corresponding to data to be recorded. CONSTITUTION:A user of this recording device inputs characters through an input means 19 before starting actual recording or after starting the recording of a series of pieces of music. The inputted characters are stored in a buffer RAM 13. On the other hand, the U-TOC sector of a disk 1 is constituted so that character information can be recorded in the sector corresponding to each managed piece of music. Therefore, the character information stored in the RAM 13 is written in the U-TOC sector of the disk 1 corresponding to the recorded information about each piece of music. These operations are controlled by means of a system controller 11 and memory controller 12.

Abstract: PURPOSE:To prevent the intermission of reproduced sound and to improve an earthquake resistance function by setting an outermost circumferential segment not recorded yet to be a head segment and linking other segments in the addressing order when unrecorded areas are linked. CONSTITUTION:Suppose that a disk on which two musics are recorded is made up of segments 1-1, 1-2 for a 1st music and segments 2-1, 2-2, 2-3 for a 2nd music. Then unrecorded areas F-1-F5 are left. The areas F-1-F5 are linked in this order by a U-TOC and when a 3rd music is recorded, the music is recorded in the above-mentioned sequence. When the 2nd music is erased, the segments 2-1 to 2-3 are unrecorded areas. In this case, the segments formed to be new unrecorded areas are not linked to the final segment F-5 of the unrecorded area so far for the management but a new link structure is formed. That is, the unrecorded at the outermost circumference is set to a 1st segment and the others are linked from the inside in the order of address. Thus, segments F-1 to F-8 are formed.
