Title: Magnetic disk device
Inventor: ARAI TAKESHI
IPC: G11B5/455
Filed: 1986-12-17
Abstract: PURPOSE:To eliminate the need for jumper setting by the type of a device and to facilitate support and maintenance by providing a counting circuit which counts the number of magnetic heads and a microprocessor which recognizes the kind of the device based on the information and informs the recognized result to a host system. CONSTITUTION:At the time of entering the power source of the device a control part 1 including the microprocessor selects a head number zero and transmits the information to a decoder 2. There, signals from the control part 1 are converted into the signals corresponding to the respective magnetic heads and the signals are transmitted to the respective magnetic heads 4 through head select lines 7-11. But all the head select lines do not have the heads concerning the type of the device. Then a head detection part 3 is provided on the head select line and checks if there is a head actually so as to return the information to the control part 1 through a head check line 6. Based on the information, the control part 1 decides whether or not the next head should be selected and also decides the type of the device according to the number of heads after a series of actions.

IPC: G11B5/84
Filed: 1988-11-25
Abstract: PURPOSE:To obtain the magnetic disk substrate made of aluminum which is improved in CSS characteristics by forming an anodized film thereon, then subjecting the film to etching with a treating soln. essentially consisting of phosphoric acid or sulfamic acid. CONSTITUTION:A base material 2 of aluminum is subjected to an anodic oxidation treatment by an oxalic acid method to form anodized films 3 which are underlying films on one or both surfaces of the base material. The anodized films are then so polished as to have 5 to 15mum film thickness and about 5 to 50Angstrom  Ra so that the more uniform and finer rough surface shapes can be easily in the ensuing etching stage. The base material of aluminum is in succession subjected to the etching by using the treating liquid essentially consisting of the phosphoric acid or sulfamic acid. The CSS (Contact Start Stop) characteristics are improved in this way.

IPC: H05K3/00
Filed: 1986-12-15
Abstract: PURPOSE:To easily and accurately detect the short-circuit position of a printed board to be measured by putting the printed board to be measured in a container and cooling the board, and detecting a rise in temperature at the short- circuit position by a noncontacting heat-sensitive scope. CONSTITUTION:The printed board 1 is put in the container 3 made of transparent synthetic resin and liquefied carbon dioxide 4 is injected into the container 3 for cooling to equalize the temperature of the printed board 1, thereby eliminating the temperature difference of the printed board 1. In this state, a current is applied to the conductor pattern 2 of the printed board 1 from a power source 5. When the temperature difference between a normal conductor pattern 2 and the short-circuit position is detected, there is a possibility that the short- circuit position is broken with a normal current, so a current controller 6 controls the supply current. Then the noncontact type heat-sensitive scope 7 which uses an infrared detector, etc., is scanned to detect the temperature difference between the conductor pattern 2 and short-circuit position, thereby detecting a fine short-circuit position.
