Title: Optical recording and reproducing device
Inventor: TAKASAGO MASAHIRO
IPC: G11B7/085
Filed: 1985-03-20
Abstract: PURPOSE:To read out the data once recorded through any recording/reproducing device by detecting an off-track stage in two stages just to interrupt the data recording action in the corresponding sector in the 1st time width and then recording again the data in case a large defect exceeding the 2nd time width is detected. CONSTITUTION:A servo stabilization compensating circuit 8 compensates a tracking error signal 5. The level comparators 17 and 18 detect the signal levels when a light spot follows a track. The 1st off-track signal 25 shows that the state of HI level '1' of the outputs (signal 23) of both comparators 17 and 18 exceeds the designated time T1. While the 2nd off-track signal 26 shows that said state of HI level '1' exceeds the time T1 and then the designated time T2. The latch circuits 27 and 28 latch both signals 25 and 26. Thus an off-track state can be detected previously even in a recording mode and the recording action is interrupted. Furthermore the data once recorded can be read out correctly by any recording/reproducing device.

Title: Scan path type flipflop circuit
Inventor: SHIMONO TAKESHI
IPC: G01R31/28
Filed: 1987-03-12
Abstract: PURPOSE:To facilitate testing, by supplying a system clock to a slave latch circuit when a scan mode is switched over to a normal mode to compose a scan path even in a non-synchronization circuit. CONSTITUTION:When a scan control signal 105 is switched from a scan mode to a normal mode, a slave latch 3 holds a value in the scan mode irrelevant to the state of a normal clock 103. When the normal clock 103 is changed from OFF to ON state, a normal data 101 is passed through to be taken in. When the OFF state of the normal clock 103 is inputted once immediately after the switching, an output A of an AND gate 12 is fixed to 1 and hence, a scan F/F 1 operates as master-slave type DF/F by the normal clock 103. Thus, a scan data 102 remains unchanged as set to a slave latch 3 during the scan operation regardless of complicated changes in the value of a master latch 2 when the mode is switched.
