摘要： A disk medium, an information recording device, and an information reproducing device are provided, which are capable of efficiently recording sub-information such as security data and, if the sub-information is set as the security information, enhancing a security performance. The disk is divided into a plurality of zones in radial directions. A logical zone count in each zone is obtained by dividing a total recordable frame count in each zone by a frame count in a unit logical zone. For example, a logical zone count N1z in a zone i is given by: N1z=Fzi/F1z where Fzi is the total frame count in the zone i, and F1z is a frame count in the logical zone. However, a value given by the formula (1) is not always an integer depending on the zone, and there might exist a frame (gap region) not used for the logical zone. Accordingly, the security data are recorded in this gap region.

摘要： An object of the present invention is to further increase the speed of tilt control while suppressing a useless tilt control operation. Values of focus bias voltages (reference bias values V1 to V6) at a plurality of radial positions P1 to P6 are obtained and stored using a reference disk with a high flatness precision. Prior to a recording and reproducing operation, the values of focus bias voltages (Fo bias values vs1 to vs6) at the radial positions P1 to P6 are obtained, and each of tilt amounts T1 to T6 at the respective radial positions is obtained from a differential value between the reference bias value and the Fo bias value at each radial position. During recording/reproduction, a radial position Pn placed immediately before the recording/reproducing position is detected. Then, tilt control is performed with a tilt amount Tn at the radial position Pn being set as the tilt amount at the recording/reproducing position.

摘要： In a magneto-optical recording medium comprising a recording layer and a reproducing layer, a transfer layer and a magnetic shielding layer are successively formed between the recording layer and the reproducing layer respectively. The reproducing layer is prepared from Gd33(Fe70Co30)67 changing from an in-plane magnetization film to a perpendicular magnetization film at 150° C., for example. The transfer layer is prepared from Gd28(Fe90Co10)72 changing from an in-plane magnetization film to a perpendicular magnetization film at 50° C., for example. The magnetic shielding layer is prepared from SiN, for example. The recording layer is prepared from Tb20(Fe90Co10)80 whose saturation magnetization is maximized around the transition temperature of 50° C. of the transfer layer. A signal can be directly recorded in the recording layer with no magnetic influence from the reproducing layer. A magnetic domain in the recording layer is transferred into the transfer layer by static magnetic interaction, and further transferred into the reproducing layer by exchange interaction. Thus, the signal can be stably reproduced in high density.

摘要： A magnetic domain of a predetermined length is formed on a magneto-optical recording medium with the phase difference altered between the rise of a laser drive signal to generate a pulsed laser beam and the fall of a magnetic head drive signal to generate a magnetic field. A phase difference optimization circuit detects an optimum phase difference corresponding to the lowest error rate from the error rate of a reproduced signal obtained by reproducing the formed magnetic domain. A magnetic head drive signal is newly generated to produce a magnetic field modulated according to a record signal based on the detected optimum phase difference. According to the generated magnetic head drive signal and the first laser drive signal, a magnetic field is applied to the magneto-optical recording medium, and a pulsed laser is directed onto the magneto-optical recording medium to record a signal.

摘要： A magneto-optical head includes an optical member, objective lens, SIL and coil. The magneto-optical head converts a laser beam to an evanescent light and directs it to a magneto-optical recording medium. Further, the magneto-optical head applies a magnetic field to the magneto-optical recording medium. When tilt is caused, it decreases the tilt angle. The optical member refracts the laser beam to a prescribed direction to be directed to the objective lens when the laser beam is displaced from a designed optical axis. The objective lens allows the laser beam to be focused onto a point on an end face of the SIL. Further, the SIL emits the evanescent light. The optical member is arranged in contact with the optical member. As a result, a signal can accurately be recorded or reproduced even when tilt is caused to an optical disk while alleviating the problem associated with the tilt.

摘要： An electronic elemental A1 has a lead electrode at the edge and a supporting member A2, positioned so that it faces the electronic element across a gap G. The supporting member A2 also has an external connecting terminal A5 at a location opposite the lead electrode A4. A resin layer A3 is positioned between electronic element A1 and supporting member A2, indented by the distance d from the edge of the electronic element A1. The resin layer bonds the electronic element (A1) and supporting member A2. The relationship of the distance d with G should satisfy this expression; d>G. A solder A6 fills the space created by the gap G between the lead electrode A4 and the external connecting terminal A5 over the distance d which is the distance from the edge of the electronic component A1, to the resin layer A3. The solder connects the lead electrode A4 and the external connecting terminal A5. No defective connection occurs between the lead electrode and the external connecting terminal when the electronic component is mounted on the printed board.
