Abstract: PROBLEM TO BE SOLVED: To inexpensively configure a material output section, and to eliminate the need of action such as mirroring. SOLUTION: The material output section of a transmission server system is inexpensively constituted of a plurality of optical disk devices (recording and playback sections) 128-1 to 128-3. When transferring material constituting a program from a material server 121 to the material output section, the material is transferred and recorded in common into the transmission optical disk devices 128-1, 128-2. Even if one of the optical disk devices 128-1, 128-2 is broken, since the same material is recorded and backed up in the other device, the need of action such as mirroring is eliminated. The optical disk device 128-3 is for emergency use. The material that is transferred from the material server 121 to the material output section completely before program start can be output as material constituting the program by utilizing the emergency optical disk device 128-3. The optical disk devices 128-1 to 128-3 can be changed in use for transmission and for emergency. COPYRIGHT: (C)2010,JPO&INPIT

Abstract translation: 要解决的问题：为了便宜地配置材料输出部分，并且消除对诸如镜像的动作的需要。 解决方案：传输服务器系统的材料输出部分由多个光盘装置（记录和重放部分）128-1至128-3廉价构成。 当将构成程序的材料从材料服务器121传送到材料输出部分时，将材料共同地传送并记录到传输光盘装置128-1,128-2中。 即使其中一个光盘装置128-1,128-2被破坏，由于在另一个装置中记录和备份相同的材料，所以消除了诸如镜像之类的动作的需要。 光盘装置128-3用于紧急使用。 可以通过利用应急光盘装置128-3将从材料服务器121传送到材料输出部分的完全程序启动之前的材料作为构成程序的材料输出。 光盘装置128-1至128-3可用于传输和紧急情况。 版权所有（C）2010，JPO＆INPIT

Abstract: PURPOSE:To efficiently use an error information recording means by providing the error information recording means recording while reducing an information amount of an older error than the information amount of the new error regarding the time when the error is detected as a reference. CONSTITUTION:The data supplied from a data supply side are processed by a prescribed format to be supplied to a magnetic recording side 28. This signal processor is provided with error detection means 40, 50, 60 detecting verious kinds of function of the magnetic recording side 28 and the error information recording means 70 constituted so as to record while reducing the information amount of time older error than the information of the new error regarding the time when the error is detected as the reference at the time of recording the error information detected by the means 40, 50, 60. Since information items constituting the error information are weighted to plural stages from an important item to an accompanying item by the error information recording means 70, and the information are erased successively from the accompanying item, the error information recording means 70 is used efficiently without excessively remaining needless information.

Abstract: PURPOSE:To surely execute the self-diagnosis in respective parts with simple operation and to improve user's operation convinience by using the self-diagnosis in a reproduction processing system and/or a recordable recording medium and executing the self-diagnosis in a record processing system. CONSTITUTION:A recording and reproducing device 1 recording and reproducing information signals DIN, DOUT on the prescribed recording medium 7 is provided with a self-diagnostic state in addition to a normal operation state (off). Then, the first self-diagnosis (mode 1) using no recording medium 7, the second self- diagnosis (mode 2) using the recording medium 7 recorded with a reference signal and/or the third self-diagnosis (mode 3) using the recordable recording medium 7 are executed. Further, the diagonoses in mechanical systems and servo systems 14-22 are executed by the first self-diagnosis (mode 1), and the diagnoses in the reproduction processing systems 2, 3, 5, 7, are executed by the second self-diagnosis (mode 2), and the diagnoses of the record processing systems 2, 3, 4, 5 are executed by the third self-diagnosis (mode 3).

Abstract: PURPOSE:To improve the reliability of recording data by adding and recording tracking data to a prescribed area other than a recording area, detecting the detection time difference of the tracking data reproduced from an adjacent recording track and correcting the deviation of tracking. CONSTITUTION:A data recorder control part 12 outputs second replenishment data PD2 from a replenishment data generation circuit 35 at the time of recording and adds them to the head of second recording data D6. A multiplexer 34 converts serial recording data into REC via a parallel/serial conversion circuit 37, supplies them to a data recorder 13 and records them on a magnetic tape 1. The data recorder control circuit 12 takes reproducing data PB reproduced from the recorder 13 at the time of reproducing into tracking information detection circuits 50A and 50B, detects the detection time of data DA and DB for each recording track and its detection time difference is detected in a comparison circuit 51. A system control cmrcuit 24 outputs a control signal to the data recorder 13 and corrects the deviation of tracking.

Abstract: PURPOSE:To improve the rate of bit errors by unloading a magnetic tape after allowing it to travel up to a starting side or a finishing side by assigning an area other than of the starting and finishing sides of the magnetic tape to an area for recording data. CONSTITUTION:A magnetic tape 1 is wound on a drum, recording tracks are obliquely formed in sequence on the magnetic tape 1, desired input data WR is recorded on a recording track or the input data WR recorded on the magnetic tape 1 is regenerated. An area AREC other than the specified area of the starting and finishing sides of the magnetic tape 1 is assigned to the recording area of the input data WR, when a recording or a regenerating operation is finished, the magnetic tape 1 is travelled up to the specified area of the starting or the finishing side, then, a cassette tape is unloaded and taken out. Thus, the load on the recording area of the magnetic tape 1 is reduced and the rate of bit errors is improved.
