Abstract: PURPOSE:To shorten a servo area, and to increase the storage capacity of a disk by allowing the reference voltage of a comparator to generate a servo ID detection signal be always a voltage value that the minimum voltage and the maximum voltage of a comparator input voltage are divided by a definite ratio, by using a reference voltage output circuit. CONSTITUTION:The reference voltage output circuit 5 outputs the voltage value that an interval between the minimum voltage and the maximum voltage of a detection output is divided by the some definite ratio. The comparator 6 compares the output of the reference voltage output circuit 5 with the detection output 4', and generates a pulse 6' as the servo ID detection signal. A position error detector 7 detects the amplitude of a reproduced signal 2a', and at the same time, when the pulse of the servo ID detection signal is inputted, the detector 7 reads out the amplitude of the reproduced signal definite time after that, and outputs a position error signal, proportional to the difference of the amplitude of a servo data part. Thus, the servo area, necessitated for exactly detecting the amplitude of the servo data part and correctly controlling the position of the magnetic head, can be shortened, and the storage capacity of the magnetic disk can be increased.

Title: Digital picture reader
Inventor: MIYAJIMA MASAMI
IPC: G06T1/00
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To provide a digital picture reader capable of selecting emphasis on read speed or that on picture quality. SOLUTION: When the storage allowable capacity of a picture memory is made not larger than a preliminarily determined prescribed value because of the speed difference between the speed of storage of picture data into the picture memory and the speed of transfer of the picture data to an external device, a first intermittent read means or a second intermittent read means is executed. The first intermittent read means obtains a high read picture quality but has a large extent of movement of a read unit U to reduce the read speed by not reading a document picture by the read unit at the time of through down and through up of a stepping motor 12.  Thus second intermittent read means obtains a high read speed but obtains the picture quality lower than that for read at a certain speed by reading the document picture while partially thinning it by the read unit U at the time of the through down and the through up of the stepping motor 12. Thus the emphasis on the read speed or that on the picture quality can be selected.
