| titleOfInvention | Magnetic tape data handling system employing dual data block buffers |
| abstract | There is disclosed a data handling system including input-output means, intermediate memory means and principal memory means, together with data transfer and processing control logic. Input and output parallel to serial and serial to parallel and code conversion capability are provided. Input-output temporary storage and data processing are provided by the intermediate memory which comprises a pair of random access memory units or the like. The principal memory is a magnetic tape system, preferably employing a magnetic tape cassette as a memory medium. The system is usable in various ways, for example as a data terminal capable of local keyboard and/or remotely controlled data storage and transmission. Data input and output may be in parallel or serial form and a variety of data rates and data code words may be accommodated without system modification. Broadly stated, for operation in the record mode, the system accumulates data in a first one of the intermediate memory units through the input-output means. When the capacity of the first unit is reached, the entire data block is transferred to the principal memory at a high speed. While data is being transferred to the principal memory from the first intermediate memory unit, data is accumulated in the second intermediate memory unit. Transfer of data from the first intermediate memory unit is completed before the capacity of the second intermediate memory unit for incoming data is reached. Thus, when the second intermediate memory unit is full, its contents are transferred to the principal memory, and data is again accumulated in the first intermediate memory. For playback, an entire block of data is transferred at high speed from the principal memory into a first intermediate memory and is thereafter provided through the input-output means to suitable data utilization devices at a data rate compatible with such devices. While data is being transmitted from the first intermediate memory unit, a data block is rapidly entered into the second intermediate memory unit. When the first unit is empty data is transmitted from the second unit, and the first unit is refilled. Among the features provided by the system are error checking and correction on a character-by-character basis, message identification (search) based on selectable identifying code characteristics and compatibility with a a variety of keyboard controlled devices or other data input and output devices, and automatic and manual data gathering and processing machinery. |
