Abstract:
In an apparatus for recording and/or reproducing a television signal with multiplex audio signals, a pilot signal is recorded on one or both of the audio tracks of a video tape in a manner to identify the mode of the multiplex audio signals and each pilot signal is detected to establish such mode when reproducing. For example, the frequency of the pilot signal may be changed for identifying different modes of the multiplex audio signals, such as, the bilingual mode and the stereo-phonic mode, with the pilot signal of selected frequency being recorded on one of the audio tracks, or the pilot signal having a certain frequency is recorded on one of the audio tracks in the case of the bilingual mode, and on the other audio track of the tape in the case of the stereo-phonic mode. In still another embodiment, the pilot signal is recorded in both audio tracks of the tape and the phase relation of the recorded pilot signals is varied to identify the mode of the multiplex audio signals.

Abstract:
In a cell detecting part (2), an end face (13a) of a cantilever (13) is previously surface treated so that a detecting nucleotide chain D can be fixed thereto. In a reaction area (10), an electric field is generated by a cathode (11) and an anode (12). A target nucleotide chain T dripped from a nozzle (3) moves to the end face (13a) while the target nucleotide chain T is stretched. When the detecting nucleotide chain D and the target nucleotide chain T are hybridized, the mass of the cantilever (13) is increased to lower a natural frequency. Thus, ac voltage is applied to the cantilever (13) to measure the change of the natural frequency. Thus, whether or not there is the hybridization is detected and the number of the hybridized target nucleotide chains T is quantitatively detected.

VIDEO TAPE RECORDER In an apparatus for recording and/or reproducing a television signal with multiplex audio signals, a pilot signal is recorded on one or both of the audio tracks of a video tape in a manner to identify the mode of the mutliplex audio signals and each pilot signal is detected to establish such mode when reproducing. For example, the frequency of the pilot signal may be changed for identifying different modes of the multiplex audio signals, such as, the bilingual mode and the stereo-phonic mode, with the pilot signal of selected frequency being recorded on one of the audio tracks or the pilot signal having a certain frequency is recorded on one of the audio tracks in the case of the bilingual mode, and on the other audio track of the tape in case of the stereo-phonic mode.

Abstract:
PROBLEM TO BE SOLVED: To permit a content provider to inexpensively provide a recording medium and to permit a user to purchase an inexpensive recording medium, even when many contents are recorded on one recording medium. SOLUTION: An optical disk 1 is provided with a reproduction permission information recording area 1e. In a contents recording area 1c, the many contents such as videos and music are recorded by the contents provider in the state in which the reproduction of all of the contents or a part of the plurality of contents is restricted, for example, the contents data are encrypted. When reproducing the contents in which the reproduction is restricted, the user acquires the reproduction permission information, for example a decryption key, from the content provider. The acquired reproduction permission information is recorded in the reproduction permission information recording area 1e of the optical disk 1 by a content reproduction device. The content reproduction device reproduces the contents when the reproduction permission information is recorded in the reproduction permission information recording area 1e for the contents instructed so as to be reproduced.
