摘要:
An ink tank holding member for holding ink tanks containing ink is made freely attachable and detachable, at the same time, having ink lead-out members for leading out ink from ink supply ports provided for the ink tanks. For this ink tank holding member, gap complementary members are made mountable to complement the difference in shapes of ink tanks to be installed on the holding member. With the structure thus arranged, it becomes possible to use the ink tank holding member for each of the cartridges commonly, hence attempting the common use of parts, at the same time, preventing effectively the ink tanks from being inclined by the provision of the gap complementary members, thus enhancing the reliability of ink supply portion, as well as preventing the degradation of performance that may be caused by erroneous insertion of ink tanks.

A magnetic disk having data record and control signal record zones configured so that the flying height of a head slider thereof varies thereby enabling recovery of control signals. The flying height of the head sliders over the control signal record zone is less than the flying height of the head slider over the data record zone yet greater than a glider height.

A magnetic disk drive device that includes a disk-shaped medium with a magnetic film formed on a surface for recording or reproducing information, and a magnetic head for recording on and reproducing information from the disk-shaped medium. The disk-shaped medium has a data recording region and a control signal recording region. The data recording region is impressed to have convex recording regions for recording data and concave guard bands for separating adjacent recording regions. The control signal recording region has impressed concavities and convexities representing tracking marks (for effecting tracking control of the magnetic head), track number indicating marks and track numbers (for identifying the tracks), and clock marks dividing one circumference into equal intervals along a path of angular movement of the magnetic head. The disk-shaped medium has reduced track pitch and increased recording capacity because the concave guard bands can be very narrow without inducing crosstalk, and the tracking marks, track number indicating marks, and clock marks are impressed as concavities and convexities along the path of angular movement of the magnetic head.

This invention provides a magnetic disk and a magnetic disk device having the magnetic disk, which is capable of suppressing the floating variation of the head slider on the magnetic disk. The magnetic disk, in which the circumferential length of the control signal recording zone has a value not exceeding the length 3/10 times that of the head slider, in which the ratio of the depth of groove on the data recording zone and the depth of groove on the control signal recording zone is 0.2 or larger and 4.7 or smaller, in which the train of the control signal recording zones are entirely or partially provided on each projected length of the head slider, which is structured so that the step difference of the land groove does not exceed 320 nm, which is provided with the land for recording data and the groove for rendering dynamic pressure to the head slider for floating just above the groove, or in which the load capacity of the head slider on the data recording zone is equal to the load capacity of the head slider on the control signal recording zone.

A camera capable of utilizing a visual line of a photographer for a photographic operation is provided. The camera includes a visual-line detecting part for detecting a visual line (fixation point) of the photographer and a correcting part for correcting a deviation between the fixation point detected by the visual-line detecting part and an actual fixation point of the photographer's eye. The correcting part operates in association with a starting operation of the camera.

The present invention is directed to a hard disc drive, in which a floating amount of a floating slider above a discrete type recording medium can be suppressed from being fluctuated to thereby stabilize a reproduced output voltage. The ratio between a maximum wavelength (L.sub.max) of an information pattern (2) of a discrete type recording medium (1) and the length L.sub.SL of a floating slider (3) in the running direction relative to the recording medium (1) is selected so as to satisfy L.sub.SL /L.sub.max >1.
摘要:
An antenna, a dielectric window, a plasma processing apparatus and a plasma processing method are capable of improving uniformity of a substrate surface processing amount in the surface of the substrate. The antenna includes the dielectric window 16; and a slot plate 20, provided on one side of the dielectric window 16, having a plurality of slots 133. The dielectric window 16 has a flat surface 146 surrounded by a ring-shaped first recess; and a plurality of second recesses 153 formed on the flat surface 146 so as to surround a center of the flat surface 146. Here, the flat surface 146 is formed on the other side of the dielectric window 16. When viewed from a thickness direction of the slot plate, a center of each second recess 153 is located within each slot 133 of the slot plate.
