摘要： A signal processor is arranged such that, after an input signal is converted in such a manner that a first high-frequency component is relatively attenuated more than a low-frequency component by a predetermined amount as compared with a state before the input of the signal, a second high-frequency component which is different from the first high-frequency component is amplified, thereby reducing a noise component without exerting an adverse effect on the signal.

摘要翻译： 信号处理器被布置成使得在输入信号被转换成使得第一高频分量比信号输入之前的状态比第一高频分量多于低频分量比预定量相对衰减预定量 ，与第一高频分量不同的第二高频分量被放大，从而降低噪声分量，而不会对信号产生不利影响。

摘要： An image signal recording and reproducing system of this invention includes an apparatus for reproducing an image signal from a recording medium on which the image signal is recorded in a recording format selected between a first recording format for forming tracks on the recording medium by recording the image signal for one picture on the recording medium and a second recording format for forming, on the recording medium, tracks greater in number than the tracks formed in the first recording format. This system has n heads each for reproducing an image signal by tracing a track on the recording medium (n: an integer greater than one), and is arranged to detect a state of reproduction performed by each of the n heads prior to a reproduction processing operation when image signals are reproduced from a plurality of tracks formed on the recording medium in the second recording format, select m heads from among the n heads in accordance with a result of detection made by the detection circuit (m: a positive integer less than n), and perform a reproduction processing operation by using the selected m heads. With this arrangement, it is possible to reproduce image signals recorded on a magnetic medium through a head having optimal characteristics from among a plurality of heads, whereby the deterioration of image quality due to nonuniformity in the characteristics of each head is prevented and the image signals can be reproduced with high quality.

摘要： The information signal recording apparatus of this invention is adapted to form a plurality of concentric recording tracks over a disc-shaped recording medium by recording information signals on the disc-shaped recording medium. This recording apparatus is arranged to first emphasize a predetermined high-band frequency component of an input information signal in accordance with the position of a recording track on such a recording medium on which the information signal is to be recorded, then implement angle modulation on the information signal, and subsequently record the angle-modulated information signal on the recording medium. Accordingly, it is possible to optimally record the information signals on the disc-shaped recording medium, anywhere from the outer circumference to the inner circumference, without involving any influence of noise. The information signal reproducing apparatus of this invention is adapted to reproduce information signals from such a disc-shaped recording medium over which a plurality of concentric recording tracks are formed. This reproducing apparatus is arranged to suppress a predetermined high-band frequency component of an information signal to be reproduced in accordance with the position of the recording track on the recording medium from which the information signal is to be reproduced. Accordingly, it is possible to optimally reproduce the information signals on the recording medium, anywhere from the outer circumference to the inner circumference, without involving any influence of noise.
