摘要： In accordance with one form of the invention, a magnetic storage medium (e.g. disc pack 250) to be degaussed is placed in a coil (200) having a central open region sufficiently large to receive the entire magnetic storage medium. The coil is energized to obtain a current therein in one direction to produce a first magnetic field of a first polarity in the region. The coil is then energized to obtain a current therein in the opposite direction to produce in the region a second magnetic field of opposite polarity. The minimum strength of the magnetic fields should be at least 500 oersetds, and preferably about 1500 oersteds. In another form of the invention, a reel of magnetic tape (350) is simultaneously rotated on its axis and subjected to an applied transverse magnetic field, substantially in the plane of the reel, the transverse magnetic field being obtained using a lateral coil (140) which passes over and under the reel and covers about half the reel. The transverse magnetic field is applied first in one direction and then in the opposite direction. An axial magnetic field, substantially parallel to the axis of the reel, is then applied, first in one direction and then in the opposite direction, the axial magnetic field being obtained using a ring-shaped coil (150) surrounding the periphery of the reel. In the preferred embodiment, the step of applying an axial magnetic field includes applying axial magnetic fields in alternating directions at successively decreasing amplitudes.

摘要： A data erasure confirmation indicator (1) is placed in a magnetic field together with a recording medium when this recording medium is placed in the magnetic field so as to erase the data recorded in the recording medium. When the indicator (1) is placed in the magnetic field of a predetermined or higher intensity, a display unit (2) changes in its display state. The indicator (1) is formed by adhering and joining a transparent film layer (5), a core layer (6) and a magnetic layer (7). The core layer (6) has a cavity portion (11), in which magnetic particles (12) are encapsulated. The magnetic particles (12) can freely move in the cavity portion (11).

摘要： One or more pairs of magnet assemblages (14 and 16) are provided with magnetized segments (21-30) arranged in a Halbach-like array. The magnet assemblages (14 and 16) define a gap (18) through which magnetic data storage media (12) pass in a direction (20) across the segments (21-30). The magnetized sides (36) of the magnet assemblages (14 and 16) face each other thereby creating strong magnetic fields which degauss the magnetic data storage media (12) passing through the gap (18).

摘要： To prevent a spindle motor from stopping rotation while data on a magnetic disk is being erased by using a permanent magnet 151. Data in the whole area of the magnetic disk 113 is erased as a consequence of the magnetic disk 113 rotating in the magnetic field of the permanent magnet 151 located so as to face a part of the magnetic disk 113. A back yoke 161 is located so as to face a base 111. The back yoke 161 gives a magnetic force to the spindle motor in the opposite direction of the magnetic force of the erasing permanent magnet 151 so that the fluid dynamic bearing spindle motor can retain the rotation as required without stopping rotation.

摘要： A bulk degausser apparatus for erasing a reel (22) of high energy magnetic tape includes a means for generating magnetic fields including a coil (L1) defining a window (34) for passage of the reel (72) of tape. The coil (L1) includes a first winding (L2) having relatively few turns and a second winding (L3), inductively coupled to the first winding (L2), and having relatively many turns. The apparatus also includes an ac power supply (82) connected to the first winding (L2) and a dc power supply (84) connected to the second winding (L3). A resonance capacitor (C1) is interconnected with the second winding (L3) for substantially balancing the inductive reactance of the second winding (L3) at the frequency of the ac power supply. The apparatus also includes an isolation relay (K3) interconnecting the capacitor (C1) and the second winding (L3) with the dc power supply, for isolating the dc power supply when the first winding (L2) is energized by the ac power supply (82). Energization of the second winding (L3) by the dc power supply (84) causes a tape (22) in the window (34) to undergo a dc magnetic field, and energization of the first winding (L2) by the ac power supply induces ac current in the second winding (L3) resulting in a reel (22) in said window (34) experiencing an ac magnetic field. A drive mechanism for translating and rotating the reel (22) of high energy magnetic tape with respect to the coil (L1), is also disclosed.
