    摘要： A write-once DVD 1 has a lead-in area 4 provided inside a data area 5 where digital information on a document, image sound or the like is recorded, which includes prepits 9 holding copy managing key information for preventing unauthorized copy from a source disk to the DVD 1. The DVD has also a test area 3 provided inside the lead-in area 4, which is used for adjusting the power characteristics of the DVD 1. In the DVD 1, information recorded in the source disk can be. physically prevented from being copied into the DVD 1 without good cause on the basis of the copy managing key information recorded in the prepits 9.

    摘要： A DVD-R 1 has a main information area 2 where data information is recorded in a track having a wobble, and first and second control data areas 3,15 each of which is disposed in an inner space closer to the disk center than the main information area 2. The information structure and physical structure of the first control area 3 are different from those of the second control area 15. In the second control area 15, predetermined physical format information and disk production information, for example, the last address of when data is written in the DVD-R 1, the maximum transfer rate or the like, are recorded. Thus, when the DVD-R 1 is reproduced by a DVD player etc., the physical format Information and disk production information etc. recorded in the second control data area 15 are read. Thereby, the disk can be precisely identified without spoiling the physical format information, the disk production information or the like, and further illegal use of the DVD or another optical disk leading up to breach of the copyright can be effectively prevented.

    摘要： A method of manufacturing a multiturn coil and a thin film magnetic head including a multiturn coil.This multiturn coil manufacturing method includes the following steps. First a laminate made up of conducting layers and insulating layers for coil is formed on a base member on a substrate and having a given inclination. Then this laminate is formed into a loop shape with a space or discontinuity thereon. In the next step, the upper part of the laminate on opposite sides of the space is removed to form a flat surface parallel to the substrate in which the ends of all the conducting layers are exposed. Finally, film conductive strips are connected between these exposed portions across the discontinuity to complete a multiturn coil.

    摘要： A magnetic head for multi-track data recording on magnetic tape is formed of a combination of two head modules, each having a linear array of thin-film transducer elements formed on a substrate, each of these arrays consisting of a mixture of write elements and read elements. These are positioned on the respective head modules such that when the head modules are combined with the substrates mutually opposing, pairs of transducer elements are formed for respective tape tracks, each pair consisting of a read and a write element. "Read-after-write" recording confirmation can thereby be implemented together with bidirectional recording operation, by using only a combination of two head modules.
