Abstract: A transistor amplifier comprising a bipolar transistor having an input electrode and a pair of output electrodes, one of the output electrodes being coupled to the gate electrode of a field effect transistor, the field effect transistor having triode-type dynamic characteristics. Respective sources of operating potential are coupled to the bipolar and field effect transistors. To stabilize the DC bias current flowing through the field effect transistor in the event of fluctuations of the operating potential supplied thereto, a portion of such fluctuations is injected into the other output electrode of the bipolar transistor.

Abstract: The signal (801) of a first code sequence of a predetermined format a part of which is dummy data is sent to a code sequence rewriting means (1802) through a code sequence decomposing means (1801). The signal (806) of a second code sequence with which the part corresponding to the dummy data in the signal (801) is supplemented is sent to the code sequence rewriting means (1802) through a control means (1805), and the dummy data in the first code sequence is rewritten to the second code sequence. For trial viewing/listening, the signal (802) from the code sequence decomposing means (1801) is selected by means of a selector switch (1808). When the second code sequence (806) is acquired by purchase of a content, the signal (803) from the code sequence rewriting means (1802) is selected. Thus trial viewing/listening of a content such as music free of danger of decryption is possible, and a high-quality content can be reproduced by acquiring a relatively small amount of data.

Abstract translation: 其中一部分是伪数据的预定格式的第一码序列的信号（801）通过码序列分解装置（1801）发送到码序列重写装置（1802）。 通过控制装置（1805）将与信号（801）中的虚拟数据相对应的部分被补充的第二码序列的信号（806）发送到码序列重写装置（1802），并且将伪数据 在第一码序列中被重写为第二码序列。 为了试验观看/收听，借助于选择器开关（1808）选择来自代码序列分解装置（1801）的信号（802）。 当通过购买内容获取第二代码序列（806）时，选择来自代码序列重写装置（1802）的信号（803）。 因此，可以对诸如音乐之类的内容进行试听观看/收听而不存在解密危险，并且可以通过获取相对少量的数据来再现高质量内容。

Abstract: A center (content supply center) (1865) for storing/managing a content is connected to user terminals (1861-1864) used by users through networks (861-867). The center (1865) sends a signal of a content for trial viewing/listening to a user terminal free or at a low price. The user terminal (1861-1864) receives the signal, and the user can select, purchase, and reproduce at high quality only the content that the user likes. Thus trial viewing/listening is possible, and the opportunity to purchase a content is enhanced since it is unnecessary to download a large amount of data with high quality from a content supply center.

Abstract: The disk recording appts. sequentially inputs data to a memory (14) at one transfer rate. This data is subsequently read out at a second, higher transfer rate and recorded to disk (2). The amounts of data read from the memory are set so that there is a writing space in memory. During playback, the recorded data are reproduced at a rate, higher than the rate for outputting the data, and stored in a memory (22). Again the amount of data read always maintains a minimum amount of data in the memory (22).

Abstract: A disc-shaped recording medium (32) has compressed audio data recording therein. The inner diameter (dI) of a data recording region (RA) is set to a value in a range of 28 to 50 mm. The outer diameter (dO) of the data recording region is set to a value corresponding to the inner diameter such that, for the lower limit value of 28 mm for the inner diameter the outer diameter is in the range of 58 to 62 mm, whereas for the upper limit value of 50 mm for the inner diameter the outer diameter is in the range of 71 to 73 mm.

Abstract: A disc-shaped recording medium (1) has a diameter of not more the 80 mm and a recording track pitch of approximately 1.6 mu m. In excess of 130 Mbytes of information is recorded in a data compressed state on the medium (1), which is rotationally driven at a constant linear velocity for recording and optically reproducing the information. A recording/reproducing apparatus for the medium (1) includes a buffer memory (23) between a data compressing circuit (23) for compressing input digital data and a recording encoding circuit (26, 27) for processing the compressed data by modulation suitable for recording, and a buffer memory (25) between a playback decoding circuit (33, 26) and a data expansion circuit (23) for expanding the compressed data to the original state. The capacity of the buffer memories (25) is selected such that recording and reproduction may continue satisfactorily even if there is a track jump during recording or reproduction.

Abstract: An optical disc includes a disc base plate (21) of a light-transmitting synthetic material having a recess to mount a magnetic plate (26), and a holding part (29a), integral with the disc base plate (21), loosely to hold the magnetic plate (26) mounted in the recess with respect to the disc base plate (21). It is possible with the present optical disc to prevent distortion of the disc base plate (21) which would otherwise be caused by the difference in thermal expansion coefficients of the two components to inhibit double refraction of the disc base plate (21) caused by such distortion so as to maintain good recording/reproducing characteristics.
