Abstract: In one embodiment, the present invention provides an event recording system that has an event-capture module, an editing module, and a media recording module. The event capture module captures an event signal, such as an audio signal from a sound event, and transforms the signal into a primary event file that is accessible as it is being formed. The editing module is communicatively connected to the event capture module. It accesses and parses the primary event file into one or more digital track files that can be recorded onto a recording media. Likewise, the media recording module is communicatively linked to the editing module for receiving the one or more digital track files from the editing module. The media recording module has a plurality of media recorders for simultaneously recording the one or more digital track files onto a plurality of recording media. This allows a plurality of recording media, with the entire event recorded upon each media, to be available shortly after the event has ended.

Abstract: Audio data which are read out from a compact disc drive are written into a hard disk drive (6) at a rate that is higher than an audio playback rate. The written audio data are read out at a rate which is higher than the audio playback rate, and then output to audio output interfaces (buffer memories). The audio output interfaces read out the audio data at the playback rate and output the data. Since the hard disk drive (6) can perform reading/writing at a rate which is sufficiently higher than the playback rate of audio data, monitoring is enabled while performing ripping.

Abstract: Before erasure of data, an optical head (6) reads file management data which manages user data from a file management data area “A” of an optical disk (2). A control unit (3) drives an optical head (6) to write the information into a specific area on the optical disc (2) to save the file management data. After saving the file management data, the optical head (6) records the data for erasing the file management data into the file management data area “A”. According to a signal from the data erasure instruction cancel key or button (42, 52), after erasure of the file management data, the optical head (6) reads out the saved file management data from the specific area of the optical disc (2), and rewrite the file management data into the file management data area “A”. Thus, even after data erasure of data, the user can use the data again before erasure by using the saved file management data.

Abstract: A recording medium storing a write protection information, and a write protection method for protecting data recorded on a recordable and/or rewritable disc from unwanted overwriting or erasing. In order for write protection of a disc in a bare state that is usually used in a cartridge having a recognition switch for write-protection, such as a DVD-RAM, write protection information is recorded in a Lead-in area, a Lead-out area or a recording information area other than a user data area of the disc, and the data is protected from unwanted overwriting or erasing using the write protection information. Also, even though the write protection information stored on a disc does not match the state of a recognition switch of a case for write-protection, the data can be prevented from unwanted overwriting or erasing. Thus, the write protection can be ensured when a recordable and/or rewritable recording medium, such as DVD-RAM, DVD-R and DVD-RW, is used in a bare state.

Abstract: In an optical disk high-speed replaying/recording apparatus, a first read data quality determining section determines a quality of read second units of digital data. Upon determination that the quality of the second units of digital data is low, a first re-reading section re-reads the first units of digital data tracks, sectors, or data blocks in the second units at a third replay speed obtained by subtracting a first predetermined speed from a second replay speed. With this, the optical disk can be replayed at a speed higher than the normal replay speed, and reproduced data can be recorded on a writable optical disk except defective data caused by reproduction defects.

Abstract: On an information recording medium, a recording area is divided in a plurality of data areas, and data is recorded on each of the data areas.

Abstract: When a detection device detects any kind of change regarding track recording after the start of the track recording, a grouping instruction is given to information attaching and generating device. Then, the information attaching and generating device attaches the same group name information to a group, in which a track where the recording has been started in an information recording medium to a track recorded at the point when the grouping instruction has been received are made to be the same group, and group control information is generated. Therefore, since the grouping is automatically performed by any kind of change regarding the track recording, a user can omit the operation that he/she performs the grouping by himself/herself, and thus the operation load of the user can be reduced.

Abstract: The rewriting counts in respective areas of a rewritable medium are uniformized. If empty areas are present on the rewritable medium rearward of a recording start position in terms of addresses, then data is recorded in those empty areas. When no empty areas become available rearward of the recording start position, data is then recorded in empty areas forward of the recording start position. The numbers of times that data is recorded in recording areas of the recording medium are thus averaged.

Abstract: There is generated a rhythm corresponding to a designated tempo and meter of a music piece to be recorded. Performance of a musical instrument is started at specific timing according to the generated rhythm, and the musical information resulting from the performance is recorded onto an MD (Mini Disk). The address on the MD read out when the performance of the music piece is started is retrieved as a start address of the music piece. After the recording, the retrieved start address is recorded onto the UTOC (User's-table-of-contents) area of the disk along with the designated tempo and meter. By reading out the start address, tempo and meter to calculate a measure number and start address of a desired measure on the basis of the read out information, display of a measure number being currently reproduced and quick access to the starting point of any desired measure can be achieved.
