Title: Magnetic disk device
Inventor: ICHIKAWA MASATOSHI
IPC: G11B21/10
Filed: 1986-10-17
Abstract: PURPOSE:To shorten a seek time and to improve positioning accuracy by providing data buffers storing position correcting amounts and outputting a seek complete signal after the amount is confirmed. CONSTITUTION:A disk 2 is divided into plural blocks through the inner-most cylinder to the outer-most cylinder. Each block is provided with the position correction data buffers 5 and 6 storing the correcting amounts by which the position of a head 1 is corrected. The buffer 5 stores data estimated according to a change in its contents, while the buffer 6 stores data updated at every time the position is corrected in the block concerned. At the time of seek, the head is seeked in the position with a little off-track amount from a specified cylinder with the aid of the buffer 5. Upon the completion of seek, the position of the head is corrected based on the difference between the contents of the buffers 5 and 6 in the block concerned, and the seek complete signal is outputted. Thus the seek time is shortened, thereby improving the positioning accuracy.

Title: Optical disk provided with synchronizing mark and synchronzing mark detection circuit
Inventor: UCHIUMI YOSHIHIRO
IPC: G11B7/24097
Filed: 1989-09-22
Abstract: PURPOSE:To deal with a photodetector with a built-in comparator without requiring adjusment by irradiating the synchronizing mark part of an optical disk provided with a synchronizing mark differing in two steps by light, and comparing the output level of the photodetector to receive this reflected light with a prescribed reference level. CONSTITUTION:The detector 11 consists of, for instance, the combination of an LED and a photodiode, and since the reflection factor of the synchronizing mark 4 differs in two steps in the circumferential direction of the disk at the part of the synchronizing mark 4, detection output a whose output level changes in the shape of a stair accompanied with the lapse of time is generated. This light detection output a is binarized as the comparison output b of 'L' when it is decided to be smaller than the reference level Vth by a comparator 12 and of 'H' when it is larger than the threshold Vth. The waveform of this output b changes for the threshold Vth according to the output level of the detector 11. Thus, by constituting a control system by using a digital circuit, the photodetector provided with the built-in comparator is dealt without requir ing the adjustment.
