Apparatus is provided for controlling a web transport system, such as a tape transport, of the type having supply and take-up reels for supplying and taking up the web, respectively, a tension control circuit for controlling the supply and take-up tension of the web, a web drive, such as a capstan, and a sensor for sensing the movement of the web as it is driven. The control apparatus includes a web drive detector for detecting the operation of the web drive and, particularly, the speed at which the web drive is driven. A comparator coupled to the sensor and the web drive detector compares the actual speed at which the web moves and the speed at which the web drive is driven to indicate when the speed at which the web moves differs from the speed at which the web drive is driven, such as when the web slips with respect to the web drive. An adjusting circuit coupled to the comparator adjusts the tension control circuit when the web speed differs from the web drive speed.

A disk recording and reproducing apparatus which realizes a simultaneous recording function with a simple pickup system. The apparatus comprises a recording and reproducing head, a first memory for receiving and storing input signals at a first rate and supplying the stored signals at a second rate higher than the first rate so as to be recorded onto a disk medium at the second rate by the head, a second memory for receiving and storing signals reproduced at the second rate by the head and outputting the stored signals at a rate lower than the second rate, and control means for controlling the head to reproduce the Nth block (N is a natural number) and then repeating, while N is repetitively incremented, a sequence of operations of reproducing the N+1th block, moving to a position of the disk medium at which the Nth block is recorded, recording the input signals supplied thereto from the first memory means at the position of the disk medium at which the Nth block is recorded, and moving to another position of the disk medium at which the N+2th block is recorded.

A method of editing a plurality of information signals recorded on a recording medium is provided. According to this method, information signals which are required for editing and which are included among the signals already recorded on the recording medium are indicated. Then such indicated signals are reproduced and recorded on the same recording medium in sequence and a recording control device is caused to recognize the area on the recording medium where the indicated signals are not newly recorded, as an empty area free of recorded signals, to thereby make the best use of the recording area of the recording medium.

A mode change-over mechanism for a tape recording and/or reproducing apparatus wherein the operating mode is selected by depressing a selected one of a plurality of push-buttons. The mechanism includes a pair of operating gears and a pair of independently movable operating members. The operating gears are associated with selected ones of plural push-buttons through respective trigger members. Movement of the first operating member in response to depression of a push-button establishes one operating mode for the recorder/reproducer; movement of the second operating member in response to another push-button establishes a second mode; movement of both operating members responsive to a third push-button establishes another mode; and further modes are obtained by movement of the first operating member through plural paths.

In a tape recording and/or reproducing apparatus for use with a tape cassette containing a supply of tape and having an opening at one side of the cassette housing along which a run of the tape is normally guided, and lids mounted on the housing for movement between closed positions for covering respective parts of the tape run and opened positions where the lids are displaced from the opening to permit the withdrawal of the tape therethrough: magnetic heads or transducers are mounted on a chassis so as to be spaced from the open side of a cassette housing when the latter is operatively positioned in respect to the chassis; tape withdrawing members are engageable with the tape run in the operatively positioned cassette housing and are operative to withdraw the tape through the open side and into engagement with the transducers; and a cassette loading device includes a cassette holder movable between an inoperative position for the insertion and removal of a cassette in the holder and an operative position where a cassette in the holder is operatively positioned, and lid opening members mechanically coupled with the holder to move between inactive positions avoiding interference with insertion and removal of a cassette in the holder in its inoperative position, and active positions in which the lid opening members open the lids of an operatively positioned cassette in response to movement of the holder to its operative position.

A tape cassette having supply and takeup reels rotatably disposed in a housing and a supply of tape wound on the reels and extending between the latter, is provided with a brake assembly which is engaged when the cassette is not in use, and which is operative in such engaged condition to securely hold the reels against rotation in the directions for unwinding the tape therefrom, while permitting substantially free rotation of each reel independently of the other in the direction for rewinding the tape on the reel.

A command from a remote terminal of an editor is supplied to a system controller in an information reproducer. The system controller controls a control circuit and a reproducing circuit, and sets address information in an address output circuit. During virtual reproduction, the system controller sets virtual address information in the address output circuit, and the virtual address information signal is output to an address input terminal of the editor. A reproduced information signal from the reproducing circuit is supplied to an information input terminal of the editor via an information output circuit.

A disk recording and reproducing apparatus which realizes a simultaneous monitoring function with a recording function with a simple pickup system is disclosed. The apparatus comprises a recording and reproducing head, a first memory for receiving and storing input signals at a first rate and supplying the stored signals at a second rate higher than the first rate so as to be recorded onto the disk medium at the second rate by means of the recording and reproducing head, a second memory for receiving and storing signals reproduced at the second rate by means of the recording and reproducing head and outputting the stored signals at a rate lower than the second rate, and a controller for controlling the recording and reproducing head to relatively scan a same portion of the disk medium twice for a predetermined period of time so that recording and reproduction occur alternately and successively at the portion of the disk medium for each predetermined number of blocks.
