A user interface method and apparatus are provided. A user interface method of a smart device includes receiving an electrical signal from an electromyography (EMG) sensor worn on a user, determining a user input based on the received electrical signal and position information about a determined position of a detected touch of the user on a touch screen, and controlling operation of the smart device in response to the determined user input.

User interface method and apparatus

An optical disk drive includes, a main body, a tray driven by a loading motor transporting a disk in or out of the main body, and a base chassis on which an optical pickup emitting a beam onto a recording surface of the disk is mounted. A rotary chassis, installed to rotate with respect to the base chassis, has a turntable on which the disk is to be placed. Also, the optical disk drive includes a skew adjustment mechanism controlling skew between the disk placed on the turntable and the optical pickup mounted on the base chassis by rotating the rotary chassis. The optical disk drive dynamically controls skew between the disk and the optical pickup so that light is incident on the disk in a precise direction, thereby increasing its performance of data recording and reproducing.

Optical disk drive having a skew adjustment function

A method for manufacturing a magnetic head recording and reproducing information on or from magnetic recording media such as a video tape, includes the steps of preparing a chip core having a contact surface with which a magnetic tape contacts and on which a gap for forming a leakage magnetic field is formed, polishing the contact surface of the chip core by using an ion etching method where the contact surface is bombarded with ions, and forming a protection layer on the contact surface, which is made of a material having high surface lubrication properties and good anti-abrasion properties. In the above method, the contamination of the head is reduced, the life span of the head is prolonged and the magnetic recording and reproducing characteristics are improved.

Method for manufacturing a magnetic head

In a head drum connection device, one end of a cable is fixed to an auxiliary circuit substrate of a head drum and the other end of the cable having a connection portion is combined with a connector shell having two pieces for supporting the connection portion in the combined state. A holder having a through-hole for fixing the connector shell at the center thereof and a binding groove for fixing a drum base to a deck are formed on a drum base. Also, a connector connected with the other end of the cable supported by the connector shell is installed on a main circuit substrate. As a result, the head drum is automatically electrically connected with the main circuit substrate when assembling the deck and the main circuit substrate.
