Title: Information alternate processing method of write protected information recording medium
Inventor: KOJIMA NOBUYUKI
IPC: G11B20/12
Filed: 1992-10-16
Abstract: PURPOSE:To improve reliability by temporarily storing data in a defective sector, which are detected during reading data from the recording medium to which a write protect is set, into a specific area and rewriting the data into a normal alternate area when the write protect is released. CONSTITUTION:When a defective sector is detected while reading the data of a cartridge 1 in which a write protect(WP) is set by a WP notch 3, data in the defective sector are temporarily stored in an alternate sector area 5. When the WP is released, the data in the area 5 are rewritten into an alternate sector in a normal user area 4. Thus, even the data in the defective sector which is detected at the time of WP are normally alternately processed. Moreover, since the area 5 is provided other than the area 4, a data writing into the area 4 is inhibited at the time of WP. Therefore, no data rewrite takes place during an alternate processing at the time of WP and the reliability of data recording is improved.

Abstract: PURPOSE:To perform stable recording by using material qualities reduced in abrasion resistance in the order of, a support having electrode needles arranged to both main surfaces thereof, the support for grasping the first row electrode needles, and the support for grasping the second row electrode needles. CONSTITUTION:The rear part of each of the first electrode needles 1a is slightly exposed with respect to the advance direction of a head at a recording time by the friction with the dielectric breakdown recording paper 4 pressed to said needle and the front part of each of said electrode needles 1a protrudes in an easily shaven state, because the contact pressure with the dielectric breakdown recording paper 4 is low and a support 2b is composed of material quality low in abrasion resistance as compared with conventional material quality. Since difference is generated between the abrasion speed of the first row electrode needles 1a and that of the support 2a behind the first row electrode needles 1a, unevenness is generated even on the surface of the support 2a in front of the second row electrode needles but, since material quality easiest to shave is used in the support 2a in front of the second row electrode needles 2b, the effect of unevenness is reduced in the periphery of the second row electrode needles 2b. The protruding quantity of both of the first row electrode needles 1a and the second row electrode needles 2b is about 5mum and, even when continuous recording is performed, no blue is generated in a character or image.

Abstract: PURPOSE:To contrive reduction in mounting height of the semiconductor device on a printed wiring substrate by a method wherein the shape of the lead to be formed is changed in the semiconductor device having the lead on one side only of the body. CONSTITUTION:In the semiconductor device 1 on which a lead 1a is formed in the reverse direction every other piece of lead, the lead 1a is provided on one side of the body 1b, one lead 1a is bent once at the position of the inserting hole 2a of a printed wiring substrate 2, other lead 1a is bent once at the position 1 mm below the body 1b, and then it is bent again at the position of the inserting hole 2a of the substrate 2. In this example, the height of mounting can be reduced by 30%, but the measurement of  L is increased in lateral direction. However, when four leads are arranged in parallel and compared in cubic volume, the mounting height can be reduced on the contrary. By forming the shape of the left and the right leads 1a asymmetrically as above- mentioned, the mounting height of the device 1 of the same body size can be reduced without changing the inserting position and the inserting interval of the inserting hole 2a of the substrate 2.
