Abstract
There is disclosed an information retrieving apparatus with an external memory such as a magnetic disk capable of rearranging information stored in memory. The apparatus is provided with a first memory for storing at least accessing data. A comparator comparts the data from the external memory with the accessing data. A second memory stores the retrieved pertinent i.e., data resulting from a comparison of the accessing data with data retrieved from the external memory. The retrieved pertinent data is supplied as retrieving data to the first memory in synchronization with the data transfer rate of the external memory to enable extraction of plural records from the external memory.
