Patent number: 6005732Abstract: Device and method for restoring data in a digital VCR is disclosed in which redundancy is provided for detection of more reliable user data. The device optimally equalizes data reproduced in the VCR, and employs comparison detection in restoring the equalized data at the present time. This is accomplished by comparing the equalized data, at the present time, to either an even series prior data or an odd series prior data which has passed through the equalizing part. Determination of the data, at the present time, as not being of a positive polarity where the prior data is determined to be of a positive polarity and determination of the data, at the present time, as not being of a negative polarity where the prior data is determined to be of a negative polarity, thereby prevents the wrong determination applied to the above determination result in restoring the data to the present time.Type: GrantFiled: November 8, 1996Date of Patent: December 21, 1999Assignee: LG Electronics Inc.Inventor: Jung Kyu Lee
