  • Patent number: 5027246
    Abstract: A thin film magnetic head for use in a running direction with respect to a magnetic recording medium and in which a first magnetic material, a non-magnetic layer, a conductor layer, and a second magnetic material layer which constitute a pair of magnetic poles in cooperation with said first magnetic material layer, are laminated on a non-magnetic substrate, has the conductor layer and the second magnetic material layer formed to be parallel to the running direction. The first magnetic layer is formed to be nonparallel to the running direction in at least an opposed surface area of the head which is to be opposed to a magnetic recording medium. The second magnetic material layer is formed so that it is opposed to the magnetic recording medium at the opposed surface area and so that the second magnetic material layer progressively extends away from the magnetic recording medium in an area of the head which is outside said opposed surface area.

  • Patent number: 3953881
    Abstract: A color picture information recording and reproducing system comprises a recording device for selectively recording color picture information and a pilot signal generator. In order to eliminate hue distortion of the reproduced color picture in case of selecting, recording, repeatedly reproducing and displaying a color picture signal of a single frame or a single field in a television broadcasting program or a still picture broadcasting program edited from different information at every frame or field, an input chrominance subcarrier and pilot signal of the output of a frequency locked signal generator are recorded on a record carrier together with an input color signal. The phase of the reproduced chrominance subcarrier is made continuous between adjacent frames or field by interleaving the pilot signal and a relation of frequency interleaving is maintained so as to eliminate phase jitter.
