Document Type and Number:
Japanese Patent JP2603612
Kind Code:
B2
Abstract:
A record carrier body is described, provided with sector addresses (12) and servo-track portions (13). As the maximum width of the servo-track portions is at least 60% of the track period (Pr), in a direction transverse to the track direction, and is at least of the order of twice the maximum width of the sector-address areas (15), it is possible to obtain an improved tracking signal in addition to a satisfactory address signal. An improved information signal can be obtained by recording the information (22) in the lands between the servo tracks.
