Patent JP-H0380414-A (JP)
Title: Tracking controller
Inventor: SASAKI KOJI
IPC: G11B5/588
Filed: 1989-08-22
Abstract: PURPOSE:To provide the tracking controller which can shorten the time for computation by comparing the tracking error data to be inputted with a tracking reference value which is the tracking error data at the time of on-tracking. CONSTITUTION:A tracking error detecting means 106 detects the off-tracking of a magnetic head 101 mounted on a piezoelectric element 102 with respect to the recording tracks on a tape. The detected tracking error data is inputted together with the reference value of the tracking from a terminal 110 to a comparing arithmetic circuit 111. The tracking reference value inputted from the terminal 110 is the tracking error data at the time of the on-tracking. The comparing arithmetic circuit 111 computes the difference between the tracking error data and the tracking reference value and inputs the result of the computation processing thereof to a function generating circuit 112. The processing time is shortened by as much as the processing to change the reference value of the comparing arithmetic circuit 111 is not executed. The scanning position of a playback head is thus retracted to the on-track position.

Abstract: PROBLEM TO BE SOLVED: To allow the method to have provision for all expected events by applying error check to a signal subjected to correction processing and selecting an input signal for an error check circuit providing an output of a correct error check result so as to conduct reception processing. SOLUTION: A demodulator 21 demodulates a reception signal and gives the result to a 1st error check circuit 22 and an error correction coder 23. If the received signal is not the information provided with error correction information by a transmitter 1, the circuit 22 provides an output denoting it that the check result is correct. If the received signal is the information provided with error correction information by the transmitter 1, the circuit 22 provides an output denoting it that the check result is not correct. On the other hand, the coder 23 tries to conduct error correction decoding and provides an output to a 2nd error check circuit 24.  When an output of the demodulator 21 is a signal provided with error correction information, the circuit 24 provides an output of denoting it that the check result is correct and when the output of the demodulator 21 is a signal not provided with error correction information, the circuit 24 provides an output of denoting it that the check result is not correct. A 2nd signal selection circuit 25 selects either an input of the circuit 22 or an input of the circuit 24.
