を行うデイジタル・オーデイオ・テープデツキが
種々開発されている。 In recent years, the size of magnetic heads in magnetic recording and reproducing devices has been reduced, as exemplified by thin film magnetic heads made using microfabrication technology. Coupled with improvements in the recording characteristics of magnetic recording media and advances in microprocessor technology, digital recording devices with significantly improved quality have been developed. Among such devices, various digital audio tape decks have been developed, for example, which record PCM signals by forming multi-channel tracks on a so-called compact cassette tape.

ラツキング制御が必要となる。 Such a digital audio tape deck records the PCM signals in parallel by forming a channel of usually 18 to 36 tracks on the magnetic recording tape. The track width of each channel is approximately 50 .mu.m to 100 .mu.m. For this reason,
In order to accurately trace such minute tracks, it is necessary to control the tracking of the magnetic head, taking into consideration variations in the width of the tape itself and compatibility between various tapes and devices.

そこで従来、第１図に示す如き構造の磁気ヘツ

A reproduction head 5 made of a thin film head is provided on the front surface of the head mounting block, and a drive plate 6 is provided on one side thereof. This drive plate 6 is connected to the upper end of the drive coil 7a of the voice coil motor 7. Tracking control is performed by driving the voice coil motor 7 based on a tracking error signal or the like to move the reproduction head 5 up and down.

生じた。 However, the conventional device configured in this manner has the following problems. That is, so-called cassette tapes in which a magnetic recording tape is housed in a cassette case are not sufficiently prevented from moving in a direction perpendicular to the direction in which the tape moves within the cassette case (hereinafter referred to as the tracking direction). For this reason, even if the running position of the tape is mechanically regulated with high precision, it may vary depending on the surface condition of the tape, the presence or absence of pads, internal conditions such as tape tension, and external conditions such as temperature and humidity. During tracking control, a problem occurred in that the tape itself also moved along with the moving playback head 5. As a result, a problem arose in that stable tracking control was not performed.

ヘツド装置を提供することにある。 The present invention has been made to address such problems, and its purpose is to prevent the movement of the recording medium due to tracking control of the magnetic head, and to provide a magnetic recording medium that enables stable tracking. The object of the present invention is to provide a head device.

移動させるようにしたことを特徴としている。 The present invention provides a sliding member that slides on a recording medium near a magnetic head whose movement is controlled by a tracking mechanism, and moves this sliding member in a direction opposite to the direction of movement of the magnetic head under tracking control. The feature is that it is made to do.

れる。 Thus, according to the present invention, when the magnetic head is tracking, the sliding member moves in the opposite direction to the magnetic head, so that the force exerted by the magnetic head on the recording medium in the tracking direction is offset. Therefore, even if tracking control is performed by moving the magnetic head, the recording medium will not move in the tracking direction accordingly.
Stable tracking becomes possible. In addition, since the configuration is simple, it is highly practical and provides great effects that cannot be expected from conventional devices.

されることになる。 The magnetic head device constructed as described above is used by bringing the curvature surfaces of the reproducing head 11 and sliding contact member 12 into sliding contact with a magnetic tape (not shown). This magnetic tape is driven to run in the left and right directions in the figure. However, the control head of the playback head 11 is
Control signals are detected from control tracks on the magnetic tape. A tracking servo circuit (not shown) uses this control signal to generate first and second tracking error signals having opposite phases to each other.
S 1 and S 2 are generated, and these S 1 and S 2 are sent to voice coil motors 15 and 16, respectively. As a result, the reproducing head 11 and the sliding member 12 are moved in opposite directions. At this time, the moving forces that the magnetic tape receives from the reproducing head 11 and the sliding contact member 12 in the tracking direction are in opposite directions and are exactly canceled out, so that the magnetic tape does not move in the tracking direction. Therefore, by this movement, the reproducing head 11 is accurately positioned on the recording track, that is, the reproducing head 11 is accurately tracked.
