    摘要： An electrostatic information recording medium (3) in which a charge retaining layer (11) having high insulating properties is laminated on an electrode (13) is disclosed, as is an electrostatic information recording/reproducing process wherein, while the electrostatic information recording medium (3) is positioned in opposition to a photosensitive member (1) in which a photoconductive layer (2) is laminated on a transparent electrode (7), the recording medium (3) is subjected to information exposure with the application of voltage (17) between the electrodes (13 and 7) to accumulate electrostatic charges thereon depending upon the dosage of said information exposure, and the electrostatic information thus accumulated is reproduced by potential reading. The electrostatic information recording medium (3) has an information density as expressed in terms of a high recording capacity of the order of 8 x 10⁸ bits/cm², and makes it possible to process information in a planar state so that analog or digital information such as characters, line pictures, images, (0.1) information and sounds can be accumulated in the form of electrostatic charges. With this electrostatic information recording medium (3), it is possible to obtain information of high quality and resolving power because of the information being accumulable in electrostatic charge units. Due to its high charge retainability, it is further possible to store information permanently. Still further, it is possible to make inexpensive and simple recording/reproducing systems, since information can be output by reading local potentials of electrostatic latent images at any time and any scanning density.

    摘要： A segmentation system in which, in recording a PCM audio signal on a magnetic tape or the like, a signal divided in 5 per field is divided into 4 segments per field with high capabilities of error correction and a mean value interpolation for burst errors etc. Regarding the signal of a deep-layer record PCM format, in which each subframe (3 in Figs. 1(a) - 1(c)) is formed of 30 blocks of only even data or odd data and in which data frames (4) each including 1 subframe of the even data and 1 subframe of the odd data in combination are formed in the number of 5 per frame, the even data items are arranged in the first half part of a PCM record area on the tape, and the odd data items in the latter half part. Further, each superblock (1) is constituted by 2 blocks adjacent to each other, a C2 parity (22) of 3 superblocks being an error correcting parity is extracted from 1 subframe, with every 4 of the remaining 12 superblocks forming 1 area block (2), and the 3 area blocks are located in 3 segments differing from one another. In the case where the PCM audio signal is recorded by an HD VTR or the like by utilizing the signal processing of the deep-layer record PCM format, the segmentation warrants high capabilities for mean value interpolation and error correction for burst errors etc.

    摘要： 2.1. Zum Verbessern der Audiosignalübertragung werden bei Heim-Videorecordern, in den Schrägspuren neben dem Videosignal zusätzlich Audiosignale nach dem HiFi-Tiefenmultiplex-Verfahren aufgezeichnet bzw. abgetastet.
    Zusätzliche rotierende Köpfe zeichnen das Audiosignal in die Tiefe der Magnetschicht und die Videoköpfe beschreiben das Band mit dem Videosignal an der Oberfläche.
    Die Erfindung ermöglicht es, auf diese zusätzlichen Köpfe nebst elektronischen und mechanischem Zubehör zu verzichten, verbessert das Übersprechverhalten, verhindert Kopfwechselprobleme und gewährleistet die volle Kompatibilität zum bestehenden System.
