摘要:
In video/audio information such as a movie in a mobile terminal connected to a terminal of a seat terminal for a mobile terminal, the video is converted into video data and transmitted to a seat terminal of a front seat via a transmission path. The video data are decoded by a video decoder of the seat terminal of the front seat and displayed on a video display section. Furthermore, audio is listened to by a user via a headphone of the user's own seat.

Aspects of the present embodiments are related to manufacturing methods of magnetic recording media. The manufacturing method of a magnetic recording medium includes a step of stacking a soft magnetic backing layer, an intermediate layer, a first recording layer having a perpendicular magnetic anisotropy, an exchange coupling force control layer including ruthenium, and a second recording layer having a perpendicular magnetic anisotropy on a substrate in order. A gas pressure of a process gas when the exchange coupling force control layer is being formed is higher than the gas pressure of the process gas when being normally used.

The vertical magnetic recording medium includes a first recording layer 16 having an easy magnetization axis directed vertical to a surface of the substrate 10, a second recording layer 20 formed over the first recording layer 16 and having an easy magnetization axis directed in-plane of the substrate 10 or oblique to the surface of the substrate 10, and a third recording layer 24 formed over the second recording layer 20 and having an easy magnetization axis directed vertical to the surface of the substrate 10, whereby the vertical magnetization recording medium can improve the reproduction output and can prevent the degradation of the signal quality due to the reproduction output decrease.
摘要:
The magnetic recording medium comprises a first recording layer 16, a second recording layer 20 forming ferromagnetic coupling with the first recording layer, and an intermediate layer 18 formed between the first recording layer 16 and the second recording layer 20 and including non-magnetic layers 18a, 18b formed between the first recording layer 16 and the non-magnetic layer 18b and between the non-magnetic layer 18b and the second recording layer 20. Thus, the reproduction output of the vertical magnetic recording medium can be improved. The constitutions of the ferromagnetic layer and the non-magnetic layer of the intermediate layer are suitably controlled, whereby the S/N ratio of the vertical magnetic recording medium can be also improved.
