Title: Disk, discriminating method therefor, discriminating device therefor, and reproducing device therefor
Inventor: OZAKI KAZUHISA
IPC: G06F21/10
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent a disk from being copied illicitly by discriminating it well, to cope with simple equipment, and to maintain interchangeability. SOLUTION: Two sector numbers of a first block 24 in a read-in region are made 'X', 'Y' instead of '0', '1'. For this reason, when the first block 24 is reproduced, as it conforms to a physical format, it is dealt with as data, which can be interpreted by a disk reproducing means. However, a sector number does not conform to a logic format, it is not considered as a normal sector, it is made invalid, the block 24 cannot be recognized externally. Therefore, as this specific block 24 is not copied at the time copy, it can be discriminated whether the disk is copy disk or not by using this specific block 24.

Filed: 1979-11-22
Abstract: PURPOSE: To ensure an assured operation with a simple mechanism, by providing the intermediate stop position to the manual operation lever which gives a switching to the travelling direction of the magnetic tape and thus carrying out a pause action.  
     CONSTITUTION: The manual operation lever 30 is turned right until the 1st hollow part 30b engages the hook end 33a of the click spring 33, thus securing the reproduction mode. On the contrary, when the lever 30 is turned left until the 3rd position where the 3rd hollow part 30d engages the end 33a, the levers have the actions just opposite to the right travelling of the magnetic tape. In other words, the 1st pinch roller 14 is pressed to the 1st capstan 11, and the 1st idler 20 touches the 1st reel drive disk 6 and the 1st flywheel 9. At the same time, the 2nd pinch roller 21 and the 2nd idler 27 are made apart from the 2nd capstan 12, the 2nd reel drive disk 7 and the 2nd flywheel 10 each. Thus the magnetic tape travels in the left direction to start the backward reproduction on the 2nd track.

Filed: 1989-06-14
Abstract: PURPOSE:To surely and easily perform processing with a CRT display device by securing a constitution where the control of a connection system is defined as the communication data which are transferred among host computers and the load of the CRT control is distributed to those host computers respectively. CONSTITUTION:The display data are sent to a CRT from host computers 11 - 1n with the parallel interruption processes applied to a controller and processed in parallel up to the host data transmission/reception parts 61 - 6n. Meanwhile these data are processes in series at a data conversion part 11 and a CRT data transmission/reception part 7. Thus the windows are partly displayed in parallel via the multi-window control instead of a serial display method where each window is displayed in parallel little by little. On the other hand, the serial operation order is adopted at the parts 7 and 11 and the host computers are set in parallel at the parts 61 - 6n when the display data are sent to these computers from the CRT owing to the presence of the key input and the pick signals of a light pen.
