Inventor: TAMAKI HIROKO
IPC: H04N5/265
Filed: 1989-11-02
Abstract: PURPOSE:To output the synthesized picture of high picture quality by changing a field memory read starting point when a field is inverted. CONSTITUTION:When a field identifying means 9a identifies the field class of a field memory 6 from the phase difference of a read system synchronizing signal or a write system synchronizing signal to the field memory 6, a deciding means 8d compares the identified read system field identifying signal with the write system field identifying signal and decides the presence and absence of the field inversion. Based on a decided result, a memory read starting point changing means 8e instructs a memory read control means 9b to change the read starting point stored in a memory read starting point storing means 8b. While recovering the exchange of odd-number and even-number fields on the field memory 6, which is generated by asynchronization between the read system synchronizing signal and the write system synchronizing signal, to a normal state, write data are read out. Thus, the synchronized picture of the high picture quality can be outputted.

Title: Magnetooptical recording system and magnetic head used for the system
Inventor: WAKASUGI HIROYUKI
IPC: G11B11/10
Filed: 1990-10-25
Abstract: PURPOSE:To enable recording in a low magnetic field by sliding a magnetic head against a magnetooptical recording medium through an abrasion-resistant protective film having specific film thickness. CONSTITUTION:A magnetic head 3 is slid against magnetooptical recording medium 1 with an abrasion-resistance protective film 7 having film thickness of 0.01-50mum through the abrasion-resistant protective film 7. Since the magnetic head 3 is slid against the magnetooptical recording medium 1, a distance to a recording magnetic layer 8 is reduced sufficiently, and a magnetic field generated by the magnetic head 3 can be small. Since the magnetic head 3 is slid through the abrasion-resistant protective film 7 formed onto the magnetooptical recording medium 1, a special servo, etc., are unnecessitated, and trouble such as crush is also eliminated. Accordingly, low magnetic-field recording is enabled without requiring a flying head and a complicate servo.

The measured data are sent to a temperature displaying section 5 which displays the temperature by using LCDs, etc., and a power supply control section 7. When it is judged at the section 7 that the sent temperature is within the guaranteeing temperature range preset in the section, the temperature of the device main body is repeatedly measured with the temperature sensor 4. In case the temperature data exceeds the range, however, a buzzer 8 produces alarming sounds for a fixed period of time and, at the same time, the power supply from the power supply section 2 is discontinued.
