摘要:
There is disclosed a high resolution thermal printing device including a 128-bit uni-directional integrated circuit, which is specially ordered, instead of a general integrated circuit. The electrical connection of the device is achieved by wedge wire bonding employing wedges. The integrated circuit has a plurality of power source connecting pads which are aligned on the central portion the integrated circuit in parallel with the transverse direction thereof.
摘要:
A recording/reproducing system for multiple users is disclosed which includes a plurality of channels connected to multiple users, a data processing portion for processing a signal of input/output information of an optical disk, and an optical head portion for reading and writing the information of optical disk. The optical head portion has at least one ultra-slim, subminiature multi-head device commonly having at least two optical heads, thereby allowing individuals to process desired information at any time.
摘要:
Apparatus is disclosed for providing an optical system which drives beam collecting lens by piezo device, for focusing the beam which moves according to the rotation of reflection mirror for using beam scanning that scans the laser beam on the surface of optical magnetic tape to be always set on the surface of the tape. An optical magnetic recording system modulates an image signal and converts the modulated signal to laser signal, and drives beam collecting lens (object lens) that collects the laser data by the synchronizing signal of the image signal, so as to allow optical magnetic recording on the tape surface. An optical recording system for recording by helical scanning the collected beam of the beam collecting lens on the tape surface using polysurface rotary mirror. An optical recording and playback system picks up optically recorded data on a optical magnetic tape using a contact sensor. A magnetic recording data pick-up device having a Hall sensor array, detects optical recording data on the surface of the optical magnetic tape by approaching the surface thereof, an accumulator and a shift array for accumulating and shifting the signal from the Hall sensor array. A magnetic recording data read control circuit which controls magnetic recording pick-up device by control data recorded according to main data.
