Title: Track accessing method and information recording and reproducing device
Inventor: SAKAGAMI WATARU
IPC: G11B21/08
Filed: 1988-02-16
Abstract: PURPOSE:To remove only the track on which an error occurs from objects to be accessed without spoiling a high-speed accessing property by recognizing the positional relation between the erroneous track and an aimed track and adopting a method for approaching the aimed track from the direction in which the erroneous track does not exist. CONSTITUTION:When it is recognized that a distance is to be subjected to rough seeking when seeking operations are executed by using the positioning accuracy N of rough seeking and the address information P of a track which produces off-tracking, the address M of an aimed track and the erroneous track information P are compared with each other. When it is confirmed that the track P is within a range from M to (M+N), seeking is executed by using an address (M-N-a) (where the a is an optional positive integer) as the address of a temporary aimed track. When the track P is within a range from M to (M-N), an address (M+N+a) is used as a temporary aimed track address. Thereafter, seeking is performed by using a fine seeking means until the real aimed track address is reached. Therefore, the tracks can be used by avoiding the erroneous track only without spoiling the high-speed seeking property.
