METHOD AND APPARATUS FOR RECORDING DIGITIZED INFORMATION ON A RECORD MEDIUM ABSTRACT OF THE DISCLOSURE At least one channel of digitized information is recorded in at least one data track on a record medium by forming data blocks, each containing a predetermined number of data words representing the digitized information, and recording successive data blocks in at least one data track. A block address also is generated to identify each of the respective data blocks, this block address also being recorded with the data block in the data track. A pre- determined number of successive data blocks is recorded in the data track in a sector interval. A control signal having at least a sector address for identifying the sector interval also is generated, and this control signal is recorded in a separate control track, successive control signals being recorded in successive sector intervals. The least significant bit of the sector address is coincident with the most significant bit of the block address, such that the block address is repeated with a periodicity related to the sector interval. The combination of the sector and block addresses is used to access a desired one of the recorded data blocks. -i-
