DISK STORAGE APPARATUS HAVING SIGNALS RECORDED IN A SPECIFIC FORMAT Abstract A record disk has a plurality of concentric record tracks divided into sectors of substantially equal lengths irrespective of the radius of the record track. In a preferred form, the record tracks are banded into radial groups, with the circumferential length of sectors in the radially inwardmost record track being equal in all of the bands. All track- identifying signals (servo signals) are radially aligned in each of the groups of tracks for providing sector servoing of a head to a given track. In those embodiments employing a plurality of independently accessible disks, a tachometer is attached to the assembly with all of the disks being keyed to a tachome- ter index such that all locations on each of the disks have a specific format relationship to the key and the tachometer. Each disk is separately calibrated such that its format has a calibratable relationship to the tachometer index. Additionally, the specific format enhances radial positioning of a transducer for track selection. In a more specific form, the outermost band of tracks has the greatest radial extent for access- ing stored data. The specific format is particularly adaptable to those data processing apparatus employing fixed block length storage blocks.
