摘要： In known head drums, information signals are transmitted at the same time as the power required for the head amplifiers is transferred, using a transformer. In the head drum according to the invention, this takes place successively in a time-division multiplex mode. The energy stores, preferably capacitors (33), required for this are arranged on the rotating upper cylinder of the head drum, just like the amplifiers.

摘要： The present invention relates to a device for reading from and/or writing to recording media in disc form which has an unbalance compensation means.
The object of the invention is to propose a device of this type which has the smallest possible unbalance even when exchangeable recording media are used.
This object is achieved according to the invention by virtue of the fact that the unbalance compensation means is a centrifugal force generation means which generates a centrifugal force which is variable during operation. According to another aspect of the present invention, provision is made for the unbalance compensation means to be a positioning means for positioning the recording medium.
The field of application of the invention includes, inter alia, devices for reading from and/or writing to optical recording media such as CD, CD-ROM, DVD, DVD-ROM, DVD-RAM and the like.摘要翻译： 本发明涉及一种用于从具有不平衡补偿装置的盘形式的记录介质读取和/或写入的装置。 本发明的目的是提出一种即使在使用可交换的记录介质时也具有尽可能小的不平衡的这种类型的装置。 根据本发明，通过不平衡补偿装置是产生在操作期间可变的离心力的离心力产生装置，实现了本发明的目的。 根据本发明的另一方面，提供了作为用于定位记录介质的定位装置的不平衡补偿装置。 本发明的应用领域尤其包括用于从诸如CD，CD-ROM，DVD，DVD-ROM，DVD-RAM等光学记录介质读取和/或写入的装置。

摘要： A head drum with integrated power supply receives control signals (S,S') which control whether read/write signals are transmitted or power is transferred to the head drum. The charge state of the power storage means (33) is also controlled so that only as much energy is transferred to the head drum as is actually required.

摘要： The invention relates to a head drum for magnetic tape apparatuses. A magnetic tape apparatus should be understood to mean any apparatus in which signals, data or information in analogue and/or digital form are recorded on a magnetic tape and/or are read from the latter. The head drum works on the principle of an active scanner, i.e. the amplifiers allocated to the write/read heads rotate with the rotating upper cylinder of the head drum. In known head drums of this type, information signals are transmitted at the same time as the power required for the head amplifiers is transferred, using a transformer.
In contrast to this, in the head drum according to the invention, this takes place successively in a time-division multiplex mode. The energy stores, preferably capacitors, required for this are arranged on the rotating upper cylinder of the head drum, just like the amplifiers.
Furthermore, the invention relates to a method on the basis of which the head drum according to the invention works and to a magnetic tape apparatus which is equipped with the head drum according to the invention.摘要翻译： 本发明涉及一种用于磁带装置的磁头鼓。 磁带装置应理解为将信号，数据或模拟和/或数字形式的信息记录在磁带上和/或从后者读取的装置。 磁头鼓以有源扫描仪的原理工作，即分配给写入/读取头的放大器与磁头鼓的旋转的上部气缸一起旋转。 在这种类型的已知头鼓中，使用变压器在传输头放大器所需的功率的同时发送信息信号。 与此相反，在根据本发明的磁头鼓中，这以时分复用模式连续进行。 所需的能量存储器（优选电容器）就像放大器一样布置在磁头鼓的旋转的上部气缸上。 此外，本发明涉及根据本发明的头鼓的工作原理的方法和装备有根据本发明的磁头鼓的磁带装置。

摘要： It is the object of the invention to create a device for compensating the unbalance of plate-shaped information media which requires a low overall height, has an improved response and is very largely independent of the drive motor and disc turntable for the information medium.
This object is achieved by virtue of the fact that the means for compensating an unbalance is provided in the hold-down (P) holding the information medium on the disc turntable. The device for unbalance compensation is an autobalancer which is provided in the hold-down (P) and is formed by a circularly running groove (H), containing compensating means (A), in the hold-down (P). The diameter of the groove (H) running in a circle is preferably greater than the inside scanning diameter of the information medium (IT), and discs or balls are used as compensating means (A).
The field of application of the invention extends to recording or reproducing units with means for compensating the unbalance of plate-shaped information media such as, for example, CD ROM or DVD drives.摘要翻译： 发明内容本发明的目的是创造一种用于补偿板形信息介质的不平衡这需要一个低的总高度，具有改进的响应和非常很大程度上独立于驱动马达和盘转台的信息介质的。 这个目的是借助于factthat的装置的用于补偿不平衡的压紧（P）设置保持于盘转台上的信息介质来实现。 为不平衡补偿的装置是自动平衡器的所有其在压紧（P）提供，并且由含补偿装置（A）的圆运转凹槽（H）形成的，在所述压紧（P）。 在一个圆圈运行槽（H）的直径最好比扫描信息介质（IT）的内径大，盘或球用作补偿装置（A）。 本发明的应用领域延伸到记录或再生的装置单元，用于补偿板形信息介质的不平衡：诸如，例如，CD ROM或DVD驱动器。

摘要： The invention relates a winding drive for a material in tape form, and proceeds from the winding device of a recorder for recording and/or reproducing signals by means of a recording medium in tape form and separate winding motors for driving the winding plates. It is preferred to use for the drive of the winding motors (2) servo units constructed as open-loop control devices and/or closed-loop control devices. In accordance with the invention, these servo units are configured in such a way that they can advantageously be used for open-loop control and/or closed-loop control of the drive of the winding motor (2) even during the braking operation.
