Title: Optical disk
Inventor: ISHIDA TAKASHI
IPC: G11B7/24091
Filed: 1987-10-20
Abstract: PURPOSE:To improve the stability of tracking by making the total section length of a bit part of which optical depth is lambda/4 in a control track part shorter than the total section length of the part which is not a bit part. CONSTITUTION:The total section length of the bit part in the control track part is made to be shorter than that of the part which is not the bit part in the control track part. Therefore, when a beam is passed through this control part, as the optical depth is lambda/4 at the bit 3 part, a tracking error signal (TE) is almost zero if a tracking error is DELTAx at an A point and the TE signal is detected only at the part which is not the bit part. But, as the total section length of the part which is not the bit part in the control track part is longer than that of a bit part in the control track part, a tracking error DELTAx'' at a B point becomes smaller. Thus, the bit is not run out from an objective track and a stable tracking characteristic can be obtained.

Abstract: PURPOSE:To always insert a slave device correctly by providing projections to a part faced to the battery lid of equipment main body and one side of the battery lid, providing a groove to the other side, and causing both to be fitted in only when the battery lid is mounted in a prescribed position. CONSTITUTION:First, a charging type battery 3 is inserted into a battery storing part 2 of the slave device, a battery lid 18 is put on it, and the lid 18 is turned. Then, the storing part 2 and lid 18 are locked by a bayonet construction. In such a condition, a groove 19 of the lid 18 is formed beforehand so that a side in which its groove width is wider is made into an inserting side to a master device. When a slave device 1 is inserted into a slave device storing part 14 of a master device 13, the groove 19 is guided by a projection 20, proceeds and is fitted in. Here, when the lid 18 is not correctly fitted, since the groove 19 and projection 20 are not fitted in well, the slave device cannot be inserted. When the slave device is inserted into the storing part the right side left, the projection 20 is abutted to the bottom surface or side surface of the slave device, and the slave device cannot be inserted. Consequently, a user can recognize that the lid is not correctly mounted or that the inserting direction of the slave device is wrong.
