Method of block recording data on a magnetic tape
Abstract
Abstract A METHOD OF BLOCK RECORDING DATA ON A MAGNETIC TAPE COMPRISES (1) FEEDING DATA AT A SELECTED FIRST RATE TO A STORAGE UNIT UNTIL THERE HAS BEEN STORED A SELECTED AMOUNT LESS THAN DATA CONTAINED IN ONE BLOCK AND (2) FEEDING THE STORED DATA TO A RECORDING UNIT HAVING A TAPE TRANSPORT AT A SECOND SELECTED RATE WHICH IS FASTER THAN THE FIRST RATE WHILE CONTINUING TO FEED DATA TO THE STORAGE UNIT. THE RATES OF STORAGE AND RECORDING ARE SELECTED SO THAT THE DATA STORED IN THE STORAGE UNIT ARE EXHAUSTED SIMULTANEOUSLY WITH COMPLETION OF RECORDING OF ONE BLOCK OF DATA BY THE RECORDING UNIT. THE TAPE TRANSPORT OPERATES AT A CONTANT SPEED DURING BOTH PERIODS, THE LENGTH OF THE INTERRECORD GAP BETWEEN SUCCESSIVE BLOCKS BEING DETERMINED BY THE SELECTED STORAGE AND RECORDING RATES.
