IPC: G11B20/12
Filed: 1987-06-19
Abstract: PURPOSE:To attain normal use even when a slight flaw exists on a floppy disk by shifting a write start position sequentially for a prescribed interval each every time formatting is applied repetitively. CONSTITUTION:A CPU 15 reads an ID field 10 and a data field 11 of each sector 9 to be set to discriminate whether or not correct formatting is applied. If a flaw disabled of magnetization exists at a position a1 in the field 11, the CPU 15 detects the flaw to discriminate defective formatting to implement the formatting repetitively. In applying formatting repetitively, the location a1 of the flaw is moved from the field 11 toward the field 10 for each prescribed interval in the sector 9 and reaches then a location a3 in a gap 12. Thus, if the flaw is very slight, the floppy disk is not discriminated to be defective but normal formatting is set.

Abstract: PURPOSE:To perform high-reliability optical heterodyne communication by providing two systems of device constitution for optical heterodyne detection equipped with a polarization control function in parallel and performing instantaneous switching when polarization control by one system becomes difficult while proceeding to the other system continuously. CONSTITUTION:A driving voltage V2l impressed to a polarization control element 4a is outputted from a polarization control element driving circuit 4b to a control part 12 from the moment the branch ratio of an optical branching device 8 reaches 0:1. The control part 12 receives it and controls a polarization control element driving circuit 3b so that the driving voltage V1l of a polarization control element 3a is V2l. Thus, the states of polarization control circuits 3 and 4 are inverted at the time of the transition of the flow of signal light L4d2 accompanying the approximation of the driving voltage V1 of the polarization control element 3a to a limit voltage. Then, the flow of the signal light L2 is changed alternately between the side of the 1st photocoupler 5 and the side of the 2nd photocoupler 6 according to the change of the polarization state of the signal light L2 to perform stable optical heterodyne detection which is not broken permanently.
