Recording system for recording data on tape in a disk-recording format. |
摘要 |
<p>A system for recording data in a stream on a recording tape in the same format that data is recorded in concentric tracks on a recording disk. The system includes a read/write transducer head for reading said tape or recording or erasing thereon; transport apparatus for transporting the tape past the transducer head to cause the head to access a stream on the tape; a first sensor for sensing a beginning-of-stream indicator on the tape; a second sensor coupled to the transport means for sensing the length of tape transported past the transducer head; a first controller coupled to the first sensor for providing an initial beginning-of-segment index pulse in response to the first sensor sensing the beginning-of-stream indicator and further coupled to the second sensor when in a formatting mode for providing end-of-segment index pulses followed by additional beginning-of-segment index pulses as a function of the length of tape transported past the transducer head following each beginning-of-segment index pulse; and a second controller coupled to the first controller for responding to each beginning-of-segment index pulse when in a formatting mode by providing a recording segment signal to the transducer head for formatting a recorded stream of segments on the tape. Each segment includes a first fill field, followed by a predetermined number of sectors including identifying addresses and data, followed by a second fill field until an end-of-segment index pulse is provided by the first controller. The segment length is equivalent to the length of a concentric track on a recording disk.</p> |
