Title: Magnetic erasing head device
Inventor: YONEYAMA MITSURU
IPC: G11B5/325
Filed: 1982-05-07
Abstract: PURPOSE:To erase recording on a high coercive force magnetic tape such as metallic tape effective, by forming the plane of a magnetic erasing head to the tape in flat shape. CONSTITUTION:A front surface 6a of the magnetic erasing head 6 is made flat and the magnetic tape 8 is driven, while being pressed on the front surface 6a. A tape pressing force P in this case is strongest at edges (a), (c) of the front surface 6a and weakest at a center (b) as shown in line 9. On the other hand, the distribution of a magnetic field intensity H toward the tape driving direction is strongest at the edges (a),(c) of a magnetic core and weakest at the center (b) as shown in line 10. Thus, the part where the pressing force P of the magnetic tape 8 is strongest and the magnetic field intensity H is strongest are made coincident, allowing to improve the erasing efficiency.

Abstract: PURPOSE:To prevent the degradation of resolution by separating a luminance signal Y and a chrominance signal C by switching an inter-field operation, intra-field operation and a intra-field process using a chrominance signal extraction filter after detecting the correlation between fields. CONSTITUTION:Differences between fields which are outputted from subtracters 19, 21, and 22, are turned to the absolute values through LPFs 22, 23, and 24 by absolute value circuits 25, 26, and 27, and are inputted to a maximum value selection circuit 38 and a minimum value selection circuit 39 to detect the correlation. The output of the circuit 39 is inputted to a first signal selection circuit 29.
