How does track search work in 1st generation Philips CD players<\/p>\n
In the current \"compact-disc' player an information block to be reproduced next (here in after referred to as\r\n\"track') is searched as follows. Assume that at a specific instant trackis being reproduced and via the keys it is requested to reproduce track\r\nj, being for example greater than i. Since the numbers of the tracks on the record carrier increase from the center towards the periphery,\r\n not necessarily starting with 1, the control means know that the track numbers must be situated further towards the periphery of the\r\nrecord carrier. In order to speed up the search process the control means then control the read means so as to make radial jumps of 256 tracks. \r\nEach jump is made towards the periphery of the record carrier; and after every jump, tracking is restored and the location of the read means relative to the track \r\nis derived from the subcode. If track numbers is not yet reached, a new jump over 256 tracks towards the periphery of the record carrier is made. \r\nThis continues until after such a jump the tracks is reached, for example in that after this jump the read means are already situated at tracks.\r\nSubsequently, a backward jump over 128 tracks is made and again the number of the track at which the read means are now located is derived from the subcode. \r\nIf the read means are now located at track number j-1 a forward jump over 64 tracks is made. In this way the beginning of tracks is reached by forward or backward\r\njumps which each time become factor of 2 smaller. Such a search procedure is also referred to as the \"binary search\u201d code procedure.\r\nThis \u201cbinary search' procedure may take much time, in particular if the tracks j and i are situated far from one another.\r\nIn the foregoing reference has been made to \"jumps over a number of tracks'. It is to be noted that record carriers such as compact discs\r\ncomprise only one track which extends along the spiral path from the center towards the periphery of the record carrier. \r\nTherefore, the statement \"jumps over a number of tracks' is to be understood to mean in fact jumps which equal the size of a number of times the track pitch,\r\nwhich is the radial displacement of the read means in one revolution of the record carrier.\r\nFurther, it is to be noted that the choice of the jumps over 256 tracks is dictated by the fact that the lead-out track which is situated after the end of\r\nthe last track number on the record carrier should have a width of at least 300 tracks.\r\nUsing jumps over 256 tracks ensures that the lead-out track is always reached in the case of an outward search movement over the record carrier.<\/pre>\n <\/p>\n
