    Abstract: Shielding portions (6 and 7) are superposed on opposite sides of an elongate flexible circuit board (4) on which signal wires are formed by folding about fold lines (a and b) to provide a flexible shielded signal wire. The flexible shielded signal wire is especially suitable for transmission of signals to and from a rotary head drum of a digital audio tape recorder.

    Abstract: A method is provided for detecting and correcting error words in a data block formed of a plurality of words each consisting of or comprising a predetermined number of bits of digital signal, the block including first error check words, second error check words not completely coincident with the first words, and a third error check work. The method comprises first executing an error check by the third check word and concluding that an error is present in each of the words of the data block when an error is detected, executing second and third error checks by the respective first and second error check words, and thereupon setting one of three states, namely a state in which each of the words is correct, a state in which each of the words has an error, and a state in which it is yet undetermined whether each word is correct or has an error; and when words having errors or undetermined words are included in the first and second words series, changing the state of the words having errors or the undetermined words.

    Abstract: A reproducing device for reproducing a tape-shaped recording medium, such as a magnetic tape, has recorded on it an address information along with data on a plurality of inclined tracks. The address information is composed of a track address and a block address. The reproducing device, reading out and reproducing data from the tape-shaped recording medium, includes a reproducing unit, an address extracting unit, a memory, a driving unit and a controller. The reproducing unit reads out data from the tape-shaped reproducing medium for data reproduction. The reproducing unit has a rotary head configured for scanning plural tracks of the tape-shaped recording medium for reading out data from the recording medium. The address extracting unit extracts the address information from data read out by the reproducing unit by one scanning of the tape-shaped recording medium by the rotary head. The memory stores data read out from the reproducing unit. The data read out from the reproducing unit is written in the memory based upon the address information extracted by the address extraction unit. The driving unit runs the tape-shaped recording medium. The controller generates read-out addresses for reading out the data stored in the memory. The controller controls the driving unit based upon the address information which is extracted by the address extraction unit and which is associated with pre-set locations on the track of the tape-shaped recording medium.

    Abstract: THERE IS PROVIDED A METHOD OF MODULATING A DATA BIT SERIES CONSISTING OF A FIRST VALUE (FOR EXAMPLE 1) AND A SECOND VALUE (FOR EXAMPLE O) WHEREBY A TRANSITION IS CAUSED SO AS TO SATISFY THE FOLLOWING CONDITIONS (A) TO (D):(A) A TRANSITION IS CAUSED AT THE BOUNDRY OF A BIT CELL WHICH IS SANDWICHED BY BITS O;(B) A TRANSITION IS CAUSED AT THE CENTRAL PORITION OF A BIT CELL OF A BIT 1;(C) AMONG AN EVEN NUMBER OF BITS 1 WHICH ARE SANDWICHED BY BIT 0, A TRANSITION IS INHIBITED AT THE CENTRAL PORTION OF EACH BIT CELL OF THE LAST TWO BITS 1 AND A TRANSITION IS CAUSED AT THE BOUNDARY OF THE BIT CELLS OF THESE TWO BITS 1; AND (D) WHEN AT LEAST ONE BIT IN A PATTERN WHICH STARTS WITH THE TWO BITS 01 APPEARS AT A LOCATION NEXT TO AN EVEN NUMBER OF BITS 1 SUBSEQUENT TO A BIT 0, A TRANSITION IS CAUSED AT THE CENTRAL PORTION OF THE BIT CELL OF THE BIT 0 BETWEEN THESE TWO BITS.
