Title: Track zero detector for floppy disk device
Inventor: HAMAOKA HIROMI
IPC: G11B21/08
Filed: 1986-08-29
Abstract: PURPOSE:To contrive sure zero detection of a track without having highly accurate control of the position of a zero sensor by detecting the position of a carriage when a magnetic head is positioned at a position near the track zero of a magnetic recording medium. CONSTITUTION:The working of a floppy disk FDD is controlled by a CPU 10 of a zero detector and the track zero detecting process is carried out. The CPU 10 receives a detection signal TS for output of a track zero sensor and reads a track number T2 out of a PROM 11. A stepping motor 1 is driven continuously until an energizing phase 2 corresponding to the number T2 is detected. At the same time, the CPU 10 receives the STEP signals equivalent to two steps from a controller FDC at a position where the number T2 is detected and delivers a track zero signal TZ to the FDC. Then a seeking action is stopped after confirming that the CPU 10 has a seeking action up to the track zero position on the disk of a magnetic head 3.

Title: Recording and reproducing method for video signal
Inventor: FUKUDA HISATOSHI
IPC: H04N9/86
Filed: 1986-08-29
Abstract: PURPOSE:To prevent unrequired beat disturbance from being generated, by performing the frequency conversion of an FM video signal, and preventing the spectra of the input and the output signals of an frequency divider, and a multiplier from being superimposed, CONSTITUTION:At time of recording, the carrier frequency fs of an FM color difference signal is converted to the carrier frequency (fc+fs) higher than the fs, and after that, it is counted down to 1/n(where, fc is an arbitrary frequency). In other words, the input FM color difference signal Sa of the carrier frequency fs is counted down to 1/4, on which an FM luminance signal is added by a rotary head, and it is recorded on a recording medium as the low-pass conversion FM color difference signal Se of a carrier frequency fs/4. In such a case, the spectra of the input and the output signals of the frequency divider are sufficiently separated to each other. As in the case of above one, the spectra of the input and the output signals of the frequency divider 28 are also sufficiently separated to each other. Thereby, it is possible to prevent the unrequired beat disturbance due to the superimposing of the signal spectra from being generated.
