Title: Head assembly and magnetic disk apparatus
Inventor: KANDA HIDEKAZU
IPC: G11B5/39
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a head assembly which can prevent burning of an MR element because of static electricity. SOLUTION: The head assembly includes a suspension 34, a head slider having a magnetoresistance effect element loaded at a leading end part of the suspension 34, a pair of lead lines 50, 52 formed on the suspension 34 and having one ends connected to the magneto resistance effect element. The head assembly further includes a short-circuit pattern 60 formed on the suspension to connect the pair of lead lines 50, 52. The short-circuit pattern 60 can be easily disconnected. When the head assembly is handled singly, the pair of lead lines 50, 52 are short-circuited by the short-circuit pattern 60 and a current resulting from static electricity runs to the magneto resistance effect element. The element is accordingly prevented from being burnt.  After the head assembly is mounted to an actuator arm, the short-circuit pattern 60 is disconnected, thereby opening the pair of lead lines 50, 52 electrically.

Filed: 1991-03-06
Abstract: PURPOSE:To improve operational properties of 'off' setting in a continuous temp. setting means by setting an interval between 'off' setting and another temp. setting longer than that between one temp. setting and another one except 'off' setting. CONSTITUTION:In a continuous temp. setting means which sequentially switches temp. setting with a key switch 13 on, a switching time from 'off' to 'high' is set longer than each switching time between 'high' and 'medium' and 'low' and 'off'. Therefore, when ironing is ended, with the key switch 13 on, the temp. setting is sequentially switched to 'off' at short intervals, and at 'off', a buzzer sounds through a buzzer circuit 24 to inform a user of it. After that, as the 'off' setting is kept longer than other setting, a user is given enough time to turn off the key switch 13.

Title: Apparatus for keeping scanning means in place
Inventor: REIMONDO YAADEI
IPC: G11B21/10
Filed: 1980-03-31
Abstract: A servo control apparatus for maintaining a scanning device, such as a beam of radiation, aligned with an information recording track on a moving recording medium, such as a record disc. The apparatus is especially adapted for use in correcting for tracking deviations brought about by temperature-induced expansion and contraction of the disc, which causes the recording track being scanned to move radially outwardly or inwardly relative to the beam of radiation. In the preferred embodiment, the apparatus includes a movable mirror for oscillating the beam in a radial direction, in accordance with a periodic dither signal. This causes a corresponding variation in the intensity of the beam reflected by the disc, with the amplitude and phase angle of this intensity variation, relative to that of the dither signal, indicating the direction and magnitude of the deviation of the beam from the track centerline. Whenever the magnitude exceeds a prescribed level, a step forward or step reverse pulse signal is coupled to a stepper motor, to increment the beam in the appropriate radial direction, whereby the beam is maintained substantially aligned with the centerline of the recording track.
