摘要： A switching arrangement for automatically detecting a recordable point on a moving recording carrier includes a control circuit which is supplied with a first signal for causing detection of the recordable point and with reading pulses produced by data stored on the recording carrier to cause movement of the carrier in the forward direction after the occurrence of the first signal, while at the same time monitoring the occurrence of reading pulses. The control circuit further causes a movement of the carrier in the reverse direction when reading pulses do not occur after a predetermined interval, and causes movement of the carrier in the forward direction after a renewed occurrence of reading pulses. The control circuit provides a second signal which indicates the readiness for writing new data when the recording carrier is moved in the forward direction to such an extent that a predetermined distance is maintained between the data stored last and the data to be newly recorded.

摘要： A method and apparatus for inserting additional data between items of data stored in a store, in which the data is in the form of blocks of uniform block length, by the insertion of additional items of data which are to be inserted, as an additional block of equal block length, following a (n - 1)th block, in which a first storage of the (n)th block of the store is effected, the additional block inserted in the store in place of the (n)th block, transferring the (n)th block from the first storage thereof and effecting a second storage thereof, subsequently transferring all the following blocks individually from the store into the first storage and, following each such first storage, inserting the block contained in the second storage into the store, and transferring, in each case, the block contained in the first storage into the second storage thereof.

摘要： A MAGNETIC RECORD-READ APPARATUS AND PROCESS HAVING SUPERVISORY CONTROL CIRCUITRY TO INDICATE WHETHER INFORMATION IS RECORDED CORRECTLY. INFORMATION BITS ARE RECORDED ON SUCCESSIVE SEGMENTS OF A PREMAGNETIZED MAGNETIC TAPE. EACH RECORDED BIT IS READ AND SUPERVISORY CONTROL SIGNALS ARE THEREBY PRODUCED, WHICH ARE COMPARED TO THE RECORDING CURRENT, TO DETERMINE IF THE INFORMATION BIT HAS BEEN CORRECTLY RECORDED. BEFORE ADVANCING THE MAGNETIC TAPE TO THE NEXT SEGMENT, AN INCORRECTLY RECORDED BIT MAY BE CORRECTED. A VIBRATOR DEVICE IS UTILIZED IN OPERATIVE CONTACT WITH THE MAGNETIC TAPE TO VIBRATABLY MOVE A PORTION OF THE MAGNETIC TAPE SEGMENT OVER THE MAGNETIC RECORD-READ HEAD AFTER THE BIT HAS BEEN RECORDED, TO GENERATE THE SUPERVISORY CONTROL SIGNALS. EVALUATOR MEANS ARE UTILIZED TO EVALUATE THE SUPERVISORY CONTROL SIGNALS AND LOGIC CIRCUITRY CONSIDERS THE EVALUATION WITH RESPECT TO THE INPUT TO THE RECORDING HEAD, TO DETERMINE WHETHER OR NOT THE INFORMATION BIT IS CORRECTLY RECORDED. WHEN THE BIT IS RECORDED CORRECTLY, OR WHEN IT IS RECORDED INCORRECTLY AND IS SUBSEQUENTLY CORRECTED, THE TAPE IS ADVANCED TO RECORD THE NEXT INFORMATION BIT ON THE SUCCESSIVE SEGMENT.
